Aryabhatta's Calculation of Pi

The video tutorial explains Aryabhatta's method for approximating the ratio of circumference to diameter, known today as pi, from his work Aryabhatiya. It details the calculation process, where a circle with a diameter of 20,000 units has an approximate circumference of 62,832 units, leading to a pi value of 3.1416. Aryabhatta's contribution is highlighted as significant in the field of mathematics, emphasizing that he considered this value as an approximation.
