thats what we are on

needs to work for more than 100 miles lol

Yeah, but it is rounded, and that slight difference adds up over long distances

7.98 is a more precise figure

whats the formula that works for 24,000 miles

And if you wanted to get even more precise, there is the slight oblate shape of the earth

But approximations are fine

yeah i know its pear shaped now

but i think we should know the formula that works for a whole sphere

It depends on what you are trying to find

the amount of curve

1 mile out 8 inches 2 miles out is what? whats the real formula

need something that works with more than 100 miles

do u know what the real formula is ?

You could calculate it with the pythagorean theorem, but 7.98 inches per mile squared works fine. You square the mile because it is curved.

people are claiming we see too far so im trying to figure out the amount of curve er mile but 8 inches squared is clearly not correct

but it only works for 100 feet

sorry 100 miles

i need something that works with a whole sphere

or 24,000 miles

we arent on a 100 mile big sphere

Well, let's see.
8 inches*100^2= 80,000
7.98 inches*100^2= 79,800
200 inch difference after 100 miles. Because rounding

It is calculated from an approximately 25,000 mile circumference sphere

so 7.98 inches per mile squared wotks for a full sphere?

works

A sphere with a radius of 3,963 miles

im gonna have to research this

It assumes earth is a perfect sphere, but for general purposes, that assumption works even considering the model states it as slightly oblate

because did u see the thing i said earlier about man a man b and man c all in a straight line 1 mile apart?

man a to man b 8 inches of drop then from man b to man c 8 inches of drop but from a to c is 32 inches of drop that doesnt seem possible where did the extra amount of earth come from to drop

sorry im not great with math but reality i can handle fairly well

From the curvature.
If it was 16 inches from a to c instead of 32, it wouldn't be curve. Instead, it would be like you are on a cone, a straight line slope.

i understand why the math needs to work but in reality where did the extra earth come from somehow

from a to b its 8 inches right

and b to c is 8 inches

ur telling me that would never make a circle ?

Yes, 8 inches of drop over one mile, but a curve would have it drop away exponentially or else it would be a straight line. So, a to b, 8 inches of drop, b to c, 8 inches, a to c, 32 inches. You are thinking about this in terms of slopes on a coordinate plane, that doesn't apply here. This is a curved surface we are talking about

i tink i would be able to graph both of the formulas out to be a circle or straight line

idk like i said im gonna have to look into this more

It might be easier to see this in a picture rather than in words

well first im gonna see if i can graph out both formulas to be a straight line
