Answer:

9
$\pi$

Explanation:

The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.

EQUATION FOR AREA OF A CIRCLE:
$\pi r^(2)$

When you put it all together you get:
$\pi * 3^(2)$ which equals
$9\pi$

DO NOT MULTIPLY 9 AND PI. IT'S JUST 9
$\pi$

hope this helped :)
