Multiple choice

If the radius of circle is $\displaystyle \pi $, then its area will be:

  1. $\displaystyle \pi $
  2. $\displaystyle { \pi }^{ 2 }$
  3. $\displaystyle { \pi }^{ 3 }$
  4. $\displaystyle 3\pi $

C Correct answer
Explanation

Area = pi * r^2. If r = pi, Area = pi * (pi)^2 = pi^3.

AI explanation

Substitute the given radius value directly into the standard formula for the area of a circle, which is pi multiplied by r squared. Replacing r with pi, the expression becomes pi multiplied by pi squared. This simplifies to pi cubed.
