to find the C angle you just have to subtract 180 from angle A and angle B

2021-01-22 14:59:07 UTC

180-59-67=54 degrees again with our other angle. 180-59-112=9 degrees

2021-01-22 14:59:17 UTC

@bohemian52983 I took that last year and loved it, good luck and I know you'll do great!

2021-01-22 15:02:23 UTC

next we just have to use the sine formula but SinA/a = SinC/c and cross multiply and isolate to get SinC(a)/SinA = c and keep in mind the you have to do this twice with 54 degrees and 9 degrees

2021-01-22 15:05:42 UTC

I used 54 degrees and got a length of 12.2 9 degrees and got 2.3 which is close enough to 2.2 so the actual answer was d

2021-01-22 16:05:03 UTC

how the hell does this work

2021-01-22 16:05:26 UTC

i got 7 but there was no 7

2021-01-22 16:05:58 UTC

the last answer kills me

2021-01-22 16:06:01 UTC

🤣

2021-01-22 16:06:13 UTC

yeah, pretty accurate

2021-01-22 16:10:35 UTC

I think it would first see the larger of a or b than the minimum of c and the larger of a,b

2021-01-22 16:18:46 UTC

yeah, larger is a, so 4, then the 3 from c

2021-01-22 16:18:57 UTC

its either 6 or 7, and ive got no idea

2021-01-22 16:35:30 UTC

same bro

2021-01-22 17:28:30 UTC

I see you too have been using guns as your go to controversial topic

2021-01-22 18:15:08 UTC

There’s only 2,3,4 so I puked assume it’s 3

2021-01-22 18:17:34 UTC

It's three

2021-01-22 18:23:48 UTC

Yeah I thought it was weird fornit to be 7 since it looks like they are looking for the largest or smallest

2021-01-22 18:46:55 UTC

It’s 3, but couldn’t you have copied and pasted it to whatever Java IDE you use?

2021-01-22 19:27:18 UTC

that's cheating though, no?

2021-01-22 19:32:22 UTC

I guess it depends on the teacher/professor. I’ve had classes where we were encouraged to use any available resources

2021-01-22 19:38:17 UTC

idk

2021-01-22 20:11:37 UTC

It's not cheating when are programming at your work place

2021-01-22 20:13:33 UTC

oh well, lol

2021-01-23 00:06:32 UTC

Would anyone be kind enough to help me out with some geometry? I need to calculate the surface area of a candle. It's mostly a simply cylinder, but it has an indent, and I want to make sure I'm calculating everything properly.

2021-01-23 00:19:12 UTC

https://cdn.discordapp.com/attachments/801170141907386408/802331566369406986/unknown.png

2021-01-23 00:19:19 UTC

I created this diagram.

2021-01-23 00:23:19 UTC

**V = (𝛑1.5^2 * 4.5) - (𝛑1.25^2 * 1.25)**

2021-01-23 00:23:32 UTC

This is the equation I came up with. Can anyone verify this?

2021-01-23 00:24:22 UTC

(*V=πr^2h* is the equation for cylinder volume.)

2021-01-23 00:41:33 UTC

It's the volume of the red minus the volume of the green, so if your formula calculates that I'd say it's right

2021-01-23 00:43:24 UTC

Do you know what the functions each do?

2021-01-23 00:44:09 UTC

Thanks. That's what I did, I'm just looking for review in case someone else sees something I missed.

2021-01-23 00:44:17 UTC

**SA = (2𝛑1.5^2 + 2𝛑1.5 * 4.5) + (2𝛑1.25*1.25)**

2021-01-23 00:44:36 UTC

I believe this is what the surface area would be?

2021-01-23 00:44:43 UTC

Where'd the extra 2 come from?

2021-01-23 00:45:17 UTC

Volume is surface * height yeah

2021-01-23 00:45:46 UTC

Basically it calculates the surface area of the red cylinder then adds the surface area of the green cylinder's walls/sides.

2021-01-23 00:45:54 UTC

Since it would be necessary to count that too.

2021-01-23 00:46:28 UTC

Well the surface area their faces times their heights

2021-01-23 00:47:01 UTC

*SA (of a cylinder) = 2πrh+2πr2^2*

2021-01-23 00:47:57 UTC

I just reversed it.

2021-01-23 00:48:14 UTC

So I did *2πr2^2 + 2πrh*.

2021-01-23 00:48:29 UTC

Are you looking to find surface area or volume?

2021-01-23 00:48:34 UTC

Both.

2021-01-23 00:48:47 UTC

Oh cool lol. Took me a minute

2021-01-23 00:48:54 UTC

**V = (𝛑1.5^2 * 4.5) - (𝛑1.25^2 * 1.25)
SA = (2𝛑1.5^2 + 2𝛑1.5 * 4.5) + (2𝛑1.25*1.25)**

2021-01-23 00:49:00 UTC

These are my calculations.

2021-01-23 00:49:20 UTC

I'm not familiar with SA but volume looks fine

2021-01-23 00:49:30 UTC

Cool, thanks.

2021-01-23 00:49:52 UTC

Bonus points: do you know why pi is used in the calculations?

2021-01-23 00:50:55 UTC

It's used in cylinder measurements because cylinders are based around a circle, not some sort of shape with flat sides, and pi is..

2021-01-23 00:51:13 UTC

Well, in case I botch my definition, from Google: "Pi is the ratio of the circumference of any circle to the diameter of that circle."

2021-01-23 00:51:20 UTC

Excellent!

2021-01-23 00:51:49 UTC

Circles intrigue me because they really don't have sides like polygons do.

2021-01-23 00:52:07 UTC

Or do they have an infinite number of sides?

2021-01-23 00:52:16 UTC

Of 0 length

2021-01-23 00:52:19 UTC

🤔 Good question...

2021-01-23 00:52:57 UTC

You've got a good head on your shoulders. Never lose that curiosity!

2021-01-23 00:53:12 UTC

That's what makes great scientists and engineers.

2021-01-23 00:53:39 UTC

Thanks!

2021-01-23 00:53:52 UTC

You are correct.

2021-01-23 00:54:15 UTC

Now, reposting in comprehensive form in case someone else comes by and can vet it...

2021-01-23 00:54:25 UTC

V = (𝛑1.5^2 * 4.5) - (𝛑1.25^2 * 1.25)
SA = (2𝛑1.5^2 + 2𝛑1.5 * 4.5) + (2𝛑1.25*1.25)

2021-01-23 00:54:58 UTC

Part of an assignment for geometry class. Does this look correct?

2021-01-23 00:58:32 UTC

@WalterMelon (him/her/nigerian) yeah, math.max take the maximum of the two numbers and math.min takes the minimum

2021-01-23 00:59:38 UTC

i just cant figure out if it wants the max/min of all 3 integers or just the ones in the closest parenthesis

2021-01-23 01:00:10 UTC

The innermost would evaluate first, and the result would be used by the next one.

2021-01-23 01:00:34 UTC

Each function only operates on numbers, so the one that has only numbers goes first

2021-01-23 01:01:06 UTC

would it add them after??

2021-01-23 01:01:16 UTC

No

2021-01-23 01:01:41 UTC

Each function chooses one number

2021-01-23 01:01:55 UTC

oh, and the 2nd time around would have given me the answer?

2021-01-23 01:02:11 UTC

That's right

2021-01-23 01:02:24 UTC

ah ok, thanks, im not the best at math

2021-01-23 01:02:28 UTC

Imagine max working. What's the answer of just that?

2021-01-23 01:02:42 UTC

4

2021-01-23 01:03:19 UTC

Right. Then, the rest of the process is evaluating min(4, 3)

2021-01-23 01:03:30 UTC

so it was 3,

2021-01-23 01:03:36 UTC

Correct!

2021-01-23 01:04:13 UTC

thanks, i usually just rely on the help code my teacher provides but i gotta at least learn something thatll be on tests

2021-01-23 01:04:37 UTC

It's good to figure out what's going on, sometimes the answers give insight

2021-01-23 01:04:47 UTC

yeah

2021-01-23 01:05:08 UTC

You learning C or C++?

2021-01-23 01:05:12 UTC

Or Java?

2021-01-23 01:05:20 UTC

java main

2021-01-23 01:05:31 UTC

Nice. I work with Java sometimes.

2021-01-23 01:05:33 UTC

i gotta use something called code HS

2021-01-23 01:05:55 UTC

That sounds like a system to run code and check answers

2021-01-23 01:06:07 UTC

yeah,

2021-01-23 01:06:24 UTC

in coding, do you copy and paste alot or just write most by typing?

2021-01-23 01:06:58 UTC

Both, and sometimes the code editor will suggest to completion options.

2021-01-23 01:07:13 UTC

But the latter two are mostly time savers

2021-01-23 01:07:53 UTC

Most of the time I work on something that someone's already done, and make changes, add or remove things.

2021-01-23 01:08:04 UTC

Something someone on my team has worked on.

2021-01-23 01:08:11 UTC

ah, the codehs thing is just like a blank page, so i have to remember all the different lines and procedures i have to do. thats where i fail, i have a shoddy memory

2021-01-23 01:08:53 UTC

Stack Overflow is what I use to reference code

2021-01-23 01:09:19 UTC

It's tough, but it sticks after a while. The main importance is to know what you want to accomplish, and the syntax is secondary to some extent. There are plugins for editors called "linters" that catch little mistakes.

2021-01-23 01:09:33 UTC

Same

2021-01-23 01:10:12 UTC

oh, usually if i get something wrong i have to go and look for it, and it takes too much time with having to look all of it up and type it out
