Answer :

C) 36π u²

1) As we're given the diameter, we can find out the radius by dividing the diameter by 2. According to that, the Diameter measure is 6 units long (8 -2)

2) So now, we can plug that into the following formula:

[tex]\begin{gathered} A=\pi\cdot r^2 \\ A\text{ =}\pi\cdot6^2 \\ A=36\pi \end{gathered}[/tex]

3) Hence, the answer is 36π u²
