pi is one of letters in greek alphabet.

Wow, what a crappy answer you got.
Try this,

The most thorough list of pi tidbits that I have ever seen... because I WROTE IT as a consolidation of facts accumulated from around the internet.
I tried not to make it too mathy.
Here are two fun facts: 1) The exact value of pi is infinite. It goes on forever. 2) The figure pi is present in the base of the Egyptian pyramids although the Greeks had not discovered it yet. Erich von Daniken suggested help from space aliens, but it is now thought that the Egyptians used a measuring wheel which incorporated pi without the Egyptians knowing it.
5 (five) which it is interesting you ask because, in 1687, a french mathmatian hypothesised it would be5..and he was correct
Every circular object, item, drawing will always be aligned with Pi - it will never change
(pi)(1/pi)=1.4396 ...
the same as pi squared, which is 9.86960440109
Pi Came From The Greek People
Here are some facts and figures about pi. Pi (as a decimal) = 3.14 Pi (as a fraction) = 22/7

I can get you started with one: Nobody who knows anything about it calls it "the pi of a circle". Pi is pi.
Pi has more than a million digits to it. Its 3.14159...etc
The story of "Life of Pi" starts to get interesting when Pi finds himself stranded on a lifeboat in the middle of the ocean with a Bengal tiger named Richard Parker. The struggle for survival and the relationship that develops between Pi and the tiger is what captivates readers and viewers.
Pi itself is a very interesting number. It occurs in many areas of mathematics, including calculus, geometry and simply arithmetic. Pi is an irrational number, that is it cannot be written down in its whole form. It has an infinite amount of decimal places after the original 3. It can be used to calculate the area or circumference of a circle. Area of a circle = pi*r^2, and the circumference of a circle = 2*pi*r, where r is the radius of the circle. Another interesting factoid is that e^(i*pi) = -1, where e is the natural number and i is the square root of -1.
Well first of all you spelt pie wrong the mathmetical term of pi is spelt pi. It is also what you use to measure the radius of a circle.

that it means 3.14 and you can use on a calculator
To 8 places its value is 3.14159265. Pi is the ratio of a circle's circumference to its diameter. It's an irrational number; that means it can't be expressed as a fraction, or an exact or repeating decimal. Two convenient approximations are: Pi ≈ 22/7 = 3.142857142857142857142857... 1/Pi ≈ 113/355 (a very interesting curiosity with the first 3 odd digits!)
