Question

is pi / 2 rational or irrational?

Answer 1

Answer:

Any real number that cannot be expressed in this form is called irrational. The number π is an irrational number, so cannot be expressed as a fraction, though there are some famous rational approximations to it, namely 227 and 355113 . Since π is irrational, it follows that π2 is also irrational.
