if you take a perfect circle and divide the circumference by the diameter you get pi (3.14159.....goes on forever as far as we know) no matter how big or small your circle is, if it's a true circle this ration C=pi*D will always be true
The decimal representation of pi DOES go on for ever - not just "as far as we know". If it terminated, then pi would be a rational number, and it is not.

What is the meaning of Pi?
See the Related Link for "Answers.com: Pi" to the left and below for the answer.
Why is the pi called pi?
Pi is (probably) an abbreviation for a Greek word meaning "perimeter" or "periphery" ... the original source is not exactly clear.
Is there a pattern in pi?
No, there are no ongoing patterns. There are some micro-patterns inside pi (such as 123456789) but they have no meaning.
Fraction value of pi?
22/7 No! It's a joke. There is no fraction value for pi. Pi is an irrational number, meaning that it cannot be represented in fractional form.
Are pi's digits peridic?
The digits of pi are not periodic. Pi is an irrational constant, and if its digits were periodic, it could be expressed as a ratio of constant integers, meaning it would be rational.
