No. You have an irrational number (pi) divided by a rational one,so the quotient is irrational.

Understand what a rational number means and you'll see why.

 

 

- A rational number is one that can be written as a ratio (that's where the name comes from) of two whole numbers.   Like 0.3 is rational because you can write it as the ratio of the whole numbers 3 and 10  to get 0.3 = 3/10.   You can't write pi as a ratio of two whole numbers.So if you divided it by a whole number you'd just get another irrational number.
