Is π a rational or irrational number?

All rational numbers can be expressed as a fraction whose denominator is non zero. Whereas, pi cannot be expressed in the fraction of two integers and has no accurate decimal value, so pi is an irrational number.

Is pi a rational number Yes or no?

No matter how big your circle, the ratio of circumference to diameter is the value of Pi. Pi is an irrational number---you can't write it down as a non-infinite decimal. This means you need an approximate value for Pi.
