Pi is a constant of 3.1415926535897932384626433832795 which is usually labeled as 3.14. There would be no formula for that.
While you're breakin' down my back n'
I been rackin' out my brain
It don't matter how we make it
'Cause it always ends the same
You can push it for more mileage
But your flaps r' wearin' thin
And I could sleep on it 'til mornin'
But this nightmare never ends
Don't forget to call my lawyers
With ridiculous demands
An you can take the pity so far
But it's more than I can stand
'Cause this couchtrip's gettin' older
Tell me how long has it been
'Cause 5 years is forever
An you haven't grown up yet

An approximation would be 22/7.
no..there is definitely a formula.

Did you try a search on google.
Here is one link.
PI
There are plenty of ways to calculate Pi. When you get to Calc 3, you'll learn about series and use them to find approximations for Pi and e. If you just need to use Pi in a program, declare PI as a constant that has as many decimal places as you want of accuracy.
FAQ
"The computer programmer is a creator of universes for which he alone is responsible. Universes of virtually unlimited complexity can be created in the form of computer programs." -- Joseph Weizenbaum.
"If you cannot grok the overall structure of a program while taking a shower, you are not ready to code it." -- Richard Pattis.
There are many ways to calculate pi. Note that if you want to calculate pi during the running of your program, this may be very inefficient. Better would be to store pi as a constant and use that constant. Ofcourse you'll always work with approximations of pi.
