And what is it's significance?

Pi is an irrational number, meaning it cannot be written as a fraction a/b. When written as a decimal it really does go on forever.
It is a truly extraordinary number. If you do degree level maths then you discover it turns up all over the place - not just with circles.
I recall a mind-boggling occurence - after a proof lasting most of the lecture a simple formula popped out: e^i*pi = 1 (or maybe it's -1?).
Anyway pi is part of the fabric of maths!

Pi is the circumfrance of a circle divided by the diamater, I think. I could be (probably am) wrong with that one, and it is 3.14 (rounded a bunch). But as far as we know, it goes on forever. There have been computers that have calculated it out for thousands of decimals, but no end has been found. Do a google search for more info:)

It is the relationship of a circles diameter to its circumference. When I was at school, (many, many years ago!!), there used to be a little magazine called Mathematical Pie and it continuously ran the calculation along the bottom of every page in every issue, and never got to a final or a recurring number.

This is Pi to 50 decimal places. It goes for ever.

Pi is 22/7 or 3.14159....
yes, it goes on without any signs of repeating forever...
i once printed PI out to the millionth place. (using mathmatica)
significance? dont know. it is werid that is for sure.
e is supposed to be the same as pi, in that it goes on ad infinitum without repeat. e is the natural log. read about it too!

this is a really short beginning of pi - 3.14159265358979325... but it does go on forever. Pi represents the ratio of a circle's circumference to its diameter.

yes, it goes on forever, but you really just use 3.14 for math.
It is used for finding the circumference from the circle's diameter or radius.

Expressed as a fraction (22/7) rather than a decimal places number: no, it doesn't go on forever.

It is 3.1416.........., and does go on forever. Pi is the relationship between a circle's radius and its circumference.
