Zu Chongzhi was the Chinese mathematician who computed the value if pi.

Liu Hui of the Wei Kingdom around 265 AD.
Pi was first computed by the Greek philosopher and mathematician Archimedes.
Pi doesn't end. It has been computed as of October 2011 to ten trillion places with no discernible pattern.
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
There is some doubt about this. In the third century, the Chinese mathematician Liu Hui calculated the value of pi by inscribing a polygon with 96 sides and a 192-gon. The average of these values gave pi = 3.141864.It has been claimed that he also found pi = 3927/1250 = 3.1416. However, many scholars believe that this more accurate figure was derived by the Chinese mathematician Zu Chongzhi. in the 5th Century. Later in life, Zu Chongzhi is known to have computed π between 3.1415926 and 3.1415927, which is correct to seven decimal places.
Pi can be estimated to various levels of accuracy:3.143.14163.14159The value pi is a type of number known as an irrational number which simply means it cannot be written as a fraction. Furthermore it is not algebraic which means it is not the root of a non-zero polynomial. Numbers that are not algebraic are known as transcendental numbers. By definition Pi is the circumference of a circle divided by its diameter.There are an infinite number of possible digits to which pi can be computed: it does not terminate or repeat. To date it has been computed to as many as 10 trillion digits. For ordinary mathematics, using anything more than 10 places would only negligibly improve the accuracy of the calculations (to 10 decimal places, pi is 3.1415926536).
It is either 5 or 7, depending on whether the first "3" is counted. The value had been computed to 10 trillion places as of 2011. The first billion digits can be seen on a text file that can take up to 10 minutes to download.
The approximate value of pi is 3.14159265.
The value of pi (Ï€) is3.1415926535897932384626433832795028841971693993751.........
You get the value of pi by dividing the circumference with the diameter of a circle. pi = c/d
