you need to measure the circumference of a circle another way than diameter times pie and then divide by the diameter

Pi is an irrational number. What an irrational number is is a number that has an infinite amount of digits, but has no pattern. So, therefore, in numbers, there is no possible way to find an exact value of pi. Someone could come up with 5 trillion digits of pi, and it would still be an approximate.
The only way to write pi in it's simplest exact form is to use the greek symbol for pi.
It's quite amazing isn't it?

The exact value of pi can be written as
pi=4*arctan(1)
pi=ln(-1)/i
etc...
I know this wasn't what you are looking for but these are exact values of pi.
If you want to know pi to some decimal point you can do a taylor expansion of the arctan. This will give you pi=4*(1-1/3+1/5-1/7+1/9....)

WOW...your teacher doesn't want much does he / she ?
In any case, there is STILL an argument about the "exact" value of Pi. The latest theory is the following (there have been over 60 PROOFS that back this up...but this page isn't big enough for that)
A = (14 – ROOT 2) ÷ 4
= 3.1464466…..
Give this to your teacher, and see what they say.
Good luck !

you can calculate pi using the following formula:
pi= 4(1/1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + 1/13 - 1/15 + ....)
as of 1996 Yasumasa Kanada of the University of Tokyo had calculated pi to 6 billion decimal places.
also the Russian Chudnovsky brothers in new york are aiming to reach 1 trillion decimal places but even these are even estimates
albeit very very accurate one

If you were able to know the exact measure of the circurmference of a circle and divide it by the exact measure of the diameter of that circle, you would have the exact ratio of pi.
Unfortunately, no fraction or numbers can describe pi exactly.

There are lots of different ways to calculate pi. They all go on forever ... because the digits of pi go on forever. Computers have calculated many billions of digits of pi; I think the world record is over 1000 billion digits. Check out the sources below.

pi is a mathematical ratio. It is equal to 22 divided by 7. If you do the division, you get a decimal that has an infinite string. Therefore, you cannot find the exact value of pi, only a very good approximation.

Well Superman....er, Klark (;-}
what is possible for you is impossible for mere mortals. As we mm's see it, pi is irrational, so by definition it has no finite value.
Please enlighten us when you get to the end of the universe, the last digit of pi is there, waiting for you.

PI does not have an exact value. it is infinity and infinity does not have an exact value

Um...realistically you can't. It's a non-repeating (as far as we know at this point) decimal.
You can try any of the techniques listed here:

Others have done it to over a trillion decimals, so I really don't see the point.
