'pi' is an IRRATIONAL number. Casually this means the decimals go to infinity, and the digits are not in any regular order.
Modern pocket calculators will give 'pi' to nine decimal places.
Hence pi ~ 3.141592654....
For school work pi = 3.14 or 3.1416
For find engineering pi = 3.1416 (That is to 'ten thousands of a unit'.
'Supa Dupa' computers have calculated 'pi' to 50 billions places and still going.
1.2411 trillion digits (1,241,100,000,000) digits of pi have been dicovered.
Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way. But calculating the digits of Pi has proven to be an fascination for mathematicians throughout history. Some spent their lives calculating the digits of Pi, but until computers, less than 1,000 digits had been calculated. In 1949, a computer calculated 2,000 digits and the race was on. Millions of digits have been calculated, with the record held (as of September 1999) by a supercomputer at the University of Tokyo that calculated 206,158,430,000 digits. (first 1,000 digits). However, learning 3.141, is all that is necessary. But you can go on and on, to infinity, and never find the exact circumference of a circle. I have only memorized 205 digits of pi; and yes I do use it to find the circumference of a circle.

The first 55 digits of pi after the decimal point are: 3.1415926535897932384626433832795028841971693993751058209
pi= 3.14159265358979323846264338327950288
The estimated trillion digits of pi are 27 trillion digits. An exact equal value would require an infinite number of digits and cannot be proved to any exact trillions.
(Pi) is not an 'infinite number'. It just can't be written exactly with any finite number of digits. But there are plenty of digits available, to make your division as accurate as you want it. You can never get an exact answer, just like you can never write the exact value of (pi), but you can get as close as anyone will ever need to get.
Circumference = (pi) x (diameter)Diameter = (circumference)/(pi) = 72/pi feet, exactly.That's the only way to write the exact diameter.It can't be done with numerical digits.
The first 250 digits of pi are: 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446229489549303819644288109756659334461284756482337867831652712019091
No, because pi has no exact value, it is neverending. You can get close by using 3.14, but never will you get it exactly right. Up to date, about 4 trillion digits have been calculated.
pi is an irrational number so there are no sustained patterns in the digits of pi.
To 30 digits, pi equals 3.141592653589793238462643383279.
3.14159265358979323846 are the first 20 digits of pi.
The first eleven digits of pi are:3.141592653
1.2411 trillion digits (1,241,100,000,000) digits of pi have been dicovered.
