The Value of PI in India
The ratio of the circumference and the diameter of a circle are known as Pi, which gives its value as 3,1428571. The old Sanskrit text Baudhayana Shulba Sutra of the 6th century BCE mentions this ratio as approximately equal to 3. Aryabhatta in 499, CE worked the value of Pi to the fourth decimal place as 3.1416. Centuries later, in 825 CE Arab mathematician Mohammed Ibna Musa says that "This value has been given by the Hindus (Indians)".
