WHAT IS PI ? HOW FOUNDED IT PLS ANSWER

Answer 1

Pi is the ratio of a circle's circumference to its diameter. So, for any circle, dividing its circumference by its diameter will give you the exact same number: 3.14159…or pi. Pi is also an irrational number, which means that its value cannot be expressed exactly as a simple fraction.

The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
