Pi is denotes as (π), and is one of the most well-known mathematical constants.

Irrational numbers are those numbers that cannot be expressed in the form of p/q where p and q are integers and q ≠ 0.

The approximate value of π is 3.14159….. which is a non-terminating and non-repeating decimal. This cannot be written as a fraction of two whole numbers.

as said Irrational numbers cannot be expressed in the form of p/q ,π also cannot be expressed in p/q form.

hence, π (pi) is an irrational number.
