Why the area of a circle with a rational radius must be an irrational number?
It the radius is r then the area is pi*r*r - which is pi times a rational number. pi is an irrational number, so the multiple of pi and a rational number is irrational.
Is the circumference of a circle an irrational number?
Yes if the diameter is rational. But it need not be if the diameter is irrational. If the diameter is 3/pi units, for example, then the circumference will be (3/pi)*pi = 3 units.
Is the circumference of a circle considered to be a whole number?
No because the circumference of a circle is pi times diameter and pi is an irrational number
