i'm confused about pi.. why is it that...

a circle can have a finite length along its circumference, and a finite length that is its diameter, but the ratio between the two is infinitely specific without repeating?

i mean, 10/3 = 3.3333...  onto the infinite but at least it repeats. pi doesn't.

also, how is it that some people think that a circle is made of an infinite number of straight line segments? if you think of a square, the length from the center to one of the corners is longer than the length of a line from the center to the midpoint on the side. no matter how many sides you add, there's always going to be a difference between the length from the center to any given corner and from the center to the midpoint of any given segment. this would mean there would always be two slightly different lengths of of the radius instead of one.

what for why it does this? :3

Read about complex number theory.
Cool shit.
Taught me that all the teachers who said .999...=1 were just giant douches who failed at math in the same way that gym teachers were giant douches who fail at sports.
