Casual Random Chitchat Thread

ooh
ive always been a huge fan of marvel
but it seems after the infinity saga ended disney saw their opportunity to turn it into a cashcow
i think Guardians 3 might be the last good marvel product in a long while

i think bcs its directly related to the actual circle
so u grab the radius of the circle and do some stuff with pie and u get the perimeter or area of it
its everywhere because its the one that works i think
 
But why is it specifically the number pi that is that?
Like why isn't it something like 7.93 or even just 3?
Why specifically pi?

So, where n is the number of sides of a regular polygon, and r is the length between the center of the polygon and a vertex of the polygon, or in a circle’s case, the radius, (n • sin(360/2n)) • 2r = perimeter and (n • sin(360/2n)) • r^2 = area. It just so happens that if n = infinity, n • sin(360/2n) = pi. This is where the circumference and area formulas come from. (At least that’s what I gather from some of my old math notes.)
 
The formulas make perfect sense when you look into the concepts behind them. They’re based off the fact that you can divide a regular polygon into twice as many right triangles as the number of sides they have.
