Is there a mathematical proof for the circumfirence of a circle, without using pi?

Oh, I see, so you can get the pi and circumference by looking at a circle as a set of teeny tiny triangles. Yea, ok, I can see how that would work to determine pi. But since pi is an irrational number, any circumference we ever get will always be just an approximation. But that doesn't matter because we can calculate pi to some decimal with the polygonal method.

Ok, I accept that. Tnx!

And my theory about numbers "needing" to start repeating is the infinite monkey theory, where in an infinitely large number, there is a statistical possibility that some parts of the number will have the same digits. It would be cool if one could recognize these sets of digits, and maybe see ifthey are equally spaced, then one would have to solve the mystery of the numbers in between.

just ramblings. forget about it.

Thanks for the polygon theory :9
