I did not ask for Pi's number, or for what is the point of it (circles), I just have a long homework on which I have to write about Pi. Any help would be useful.

It's the ratio of a perfect circle's circumference to its diameter. It's an irrational number and a transcendental number, and figures prominently not just in geometry but in calculus, probability and statistics.

Pi is one half the circumference of a unit circle. In other words, if a circle has a diameter of one foot, then it's circumference is 2*Pi feet. If the diameter is one meter, then it's circumference is 2*Pi meters. The value of Pi (approximately 3.14159265) is close enough to 3 that some ancient mathematicians thought that it should be 3, and that their measurements were off.

Sure. Pi is a mathematical constant representing the ratio of a circle's circumference to its diameter.
But instead of just shelling out the same stuff you could find elsewhere... there's a great article on Pi and its origins and uses at Wikipedia.

First, try the wikipedia. Lots of good info.
There have been whole books written about pi, so you'll probably get information overload.
I remember a weird fact someplace that The Bible makes reference to pi = 3.
A fact that I use when a calculator isn't close by is that pi is dang close to 22/7, within 4/10,000!
Wiki is my recommended starting point.

Pi is simply what you get when divide a circle's circumference by its diameter. Check the wikipedia article for a ton of info!

pi= the ratio of circumference of a circle to its diameter
2pi r/ d [or] 2r = pi
pi= 22/7

Just take info from around the net
http://en.wikipedia.org/wiki/Pi isn't bad for information regarding Pi.

It's a mathmatical constant, aproximate to 3.14 and it is the ratio of a circle's perimeter to its radius.
