My dad was wondering and he said it will bug him all night so HELP!!!!!!!!!!!!

ps. i love peach pie!

(6pi) / 6
(8pi) / 8

Answer 2

In theory, you can get pi with perfect accuracy by dividing the circumference of a circle by its diameter. Unfortunately, since pi is irrational, that guarantees that the circumference or diameter is also irrational, so (1) you couldn't measure the irrational length to perfect accuracy, and (2) even if you could, the division problem would take an infinite amount of time.

A popular rational approximation is 22/7 because the numbers are small and easy to remember. Other more accurate approximations have been given in previous answers. My favorite rational approximation was given incorrectly though. It's 355/113; pretty easy to remember (there's a pattern in the digits), and it's almost 5000 times closer to pi than 22/7 is.

Answer 3

If you mean whole numbers, there is no exact answer.

22/7 is close enough for most rough work.
Also 25 / 8, 256 / 81, and 355 / 13.

But with modern calculators, just use pi = 3.141592653589793...

Answer 4

From memory, a rough approximation to Pi is 22/7 - it's close to 3 significant figures (note that it's not exact, just an approximation to make calculations easier - i.e. pre-calculator days! ;p).

Answer 5

You simply take the circumference (the distance around the circle) and divide it by it's diameter (the distance from a point on the circle to it's most distant point).

Now your Dad can sleep soundly!

Answer 6

to get PI, you divide 22 by 7

what flavor pie do you prefer ? My favorite is cherry (grin)

Answer 7

25/8 which is within .5%
