Question

Accurate value of 22/7

OR

Accurate value of hair in our body

Answer 1

The purpose of the proof is not primarily to convince its readers that 227 (or 3 17) is indeed bigger than π; systematic methods of computing the value of π exist. If one knows that π is approximately 3.14159, then it trivially follows that π < 227, which is approximately 3.142857.

Answer 2

22/7=3.14285714286.......

The value of hair in our body depends upon person to person.
