Answer 2

Answer:

π is a an irrational number.

Step-by-step explanation:

We know that,

A number is called irrational if it can not be written in the form of p/q. Where p and q are integers and q ≠ 0.

So,  

π is a irrational number.

As we know that,  π = 3.14159... this number is a non-terminating and non-recurring and it can not be expressed as p/q. 22/7 is a approx value of π.
