WORLD HISTORY

Detailed explanation-1: -Indian mathematicians Madhava and Aryabhata made very significant contributions in finding the exact value of (pi). He used mathematical calculations for facilitating religious constructions such as altars. He used different approximations of the value of for constructing circular shapes.

Detailed explanation-2: -One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for , which is a closer approximation. The Rhind Papyrus (ca.1650 BC) gives us insight into the mathematics of ancient Egypt. The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for .

Detailed explanation-3: -The value of Pi () is the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159. In a circle, if you divide the circumference (is the total distance around the circle) by the diameter, you will get exactly the same number.

Detailed explanation-4: -The most important mathematical contribution of ancient India is the invention of the decimal system of numeration, including the number zero. The unique feature of this system is the use of nine digits and a symbol zero to represent all the integral numbers by assigning a place value to the digits.

Detailed explanation-5: -It was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by the Swiss mathematician Leonhard Euler.
