Question

Why Pi is irrational ?

Answer 1

Explanation for why Pi$\left(\mathrm{\pi }\right)$ is irrational:

$\mathrm{\pi }$ is the ratio of a circle's circumference to its diameter. And it is always an approximate constant number..

$\mathrm{\pi }\approx 3.14159265359...$

It is a non-terminating non-repeating decimal number.

Hence Pi$\left(\mathrm{\pi }\right)$ is an irrational number.
