## The Value of π

π is defined as the ratio between the circumference and diameter of a circle.

Thus, π = circumference/diameter

The great Indian mathematician Aryabhatta (C.E. 476 - 550) gave an approximate value of π. He stated that π = 62832/20000, which is approximately equal to 3.1416. It is also interesting to know that using the identity of the great mathematical genius Srinivasa Ramanujan (1887 - 1920) of India, mathematicians have been able to calculate the value of π correct to million places of decimals.

As you know that π is an irrational number and its decimal expansion is non-terminating and non-repeating (non-recurring).

The value of π up to 1000 places is given below:
