Answer 1

1. the value of approximate 3.141 .the first calculation of pi was done by Archimedes of Syracuse (287-212BC) on of the greatest . mathematician began using the Greek letter π in the 1700 s .pi is the ratio of distance around a circles edge and distance across it .,...


a. Williams Jones was invented of pi.

b. the ratio of circumference of a circles to its diameter is called pi ...

c.. the pi day celebrated in march 14 th 3/14 around the world ..

d. Indian were the first to observed that perimeter of a circles increase in proportion to its diameter . the oldest of them , the baudhayayana sulabasutra claims that perimeter of a pit is 3 times its diameter .therefore approximately the value of pi is 3 .

4. we cannot write down in simple fraction that equals to pi .the approximating of 22/7 = 3.14128 is close but not accurate . ..

Answer 2

1.History:
a.William Jones in 1706
