pi=3.14159265
I don't know how to represent the symbol here on WikiAnswers, but you can see it here: http://en.wikipedia.org/wiki/Pi

'About' means 'Approximately.'. pi is about 3.14 pi is approximately 3.14 pi is NOT equal to 3.14 pi is an irrational numbers which means that the decimals go to infinity. So any value given for 'pi' is only an approximation/about. pi ~ 3.14 pi~ 3.1416 pi ~ 3.141592 pi = 3.141592....
Not from memory.
It is very had to show that but you could approximate it with 22/7. (or just round it to 3.14159265) 22/7=3.142857142857... pi=3.14159265...
Here are the first 100 digits in Pi.3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679Thank y'all for reading

The equation that is used here is Circumference = 2 pi radius or C = 2 pi r If the circumference is 16, solving for r in the equation yields: r = 16 / 2 pi Answer is r = 8 / pi and since pi = 3.28 .... you can do the math from here. Hope this helps.
