Answer:
9[tex]\pi[/tex]
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: [tex]\pi r^{2}[/tex]
When you put it all together you get: [tex]\pi * 3^{2}[/tex] which equals [tex]9\pi[/tex]
DO NOT MULTIPLY 9 AND PI. IT'S JUST 9[tex]\pi[/tex]
hope this helped :)
