Question

why pie is considered as irrational number

Answer 1

Pi (π) is an irrational number, meaning it represents a real number with a non-repeating pattern that can't fully be expressed. Although Pi has an unrepresentable number of digits in its decimal representation, it can be approximated as 3.14159. FACT: Pi represents the ratio of a circle's circumference to its diameter

Answer 2

Hi there !!

π or pi has an approximate value of
3.141592653589......

This value continues till infinity and never ends. Also, it can be noticed that the digits never repeat and never end.

According to the definition, a number is considered to be irrational if it's non terminating ( endless) and non repeating.
Since pi ( π) is non terminating and non repeating, it is an irrational number.
