It is irrational, just like pi
To find the circumference of a circle, multiply the diameter by Pi. Pi is written as 3.14 or just use the Pi button on a calculator. You could also write something to the effect of 3pi.
3.14626437 (Pi)
Minus pi. Or minus pi plus any rational number. Here is how you can figure this out (call your unknown number "x", and let "r" stand for any rational number):x + pi = r To solve for "x", simply subtract pi from both sides. That gives you: x = r - pi
Pi is the ratio of the circumference of a circle to its diameter; it can be calculated as circumference divided by diameter, or circumference/diameter. It is an irrational number which starts 3.14159265358979323846264338327050..., but it is usually approximated to 3.14 or 22/7, though using the [π] button on a calculator makes it easier to enter a fairly accurate value.
You press the SHIFT button and then you press the x10 button.

Most scientific calculators have a button for pi. So to find the circumference of a circle multiply pi by the diameter. If there is no pi button you can approximate pi as 3.14.
Pi plus 86 equals 89.14

Most likely, it means Standard Deviation. which is used in analyzing a set of data. See related link.* * * * *The Casio range, popular with GCSE and A level students in the UK, has a button marked SD. This is a toggle between decimal (D) and standard (S) form (fraction, pi).
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.

-- enter the diameter of the circle-- hit the big ' X ' for "times"-- enter (pi) with the pi button-- touch " = " ('equals')The circumference is displayed.
the same as pi squared, which is 9.86960440109
the pi button always located on the top of 'EXP' button.
pi+pi is 6.28. all that you have to do is add up the numbers.-fromama fromamzez.webs.com
