Question

Can someone check this please?

Answer 1

\[\Large 3\pi\] is incorrect

Answer 2

what did you get for the area of the whole circle?

Answer 3

I just did 30/360 * (pi)12^2 and got 3.

Answer 4

ok ignore the pi since that's already part of the answer

Answer 5

12^2 = 144

Answer 6

and 30/360 = 1/12

Answer 7

so 30/360 * 12^2 = (1/12)*144 = 144/12 = 12

Answer 8

making the final answer to be 12pi

Answer 9

\(\large \textit{area of a sector of a circle}=\cfrac{\theta \pi r^2}{360}\qquad
\begin{array}{llll}
\theta=\textit{angle in degrees}\\
r=radius
\end{array}\)

Answer 10

Answer 11
