Answer:

9\pi

Step-by-step 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 :)
