Help to see if I got the answers right or wrong..?

SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given parameters
[tex]\begin{gathered} r=12ft,\pi=\pi \\ \text{Area}=\pi r^2 \end{gathered}[/tex]STEP 2: Calculate the area of the given circle of radius 12ft
[tex]\begin{gathered} \text{Area}=\pi r^2 \\ By\text{ substitution,} \\ \text{Area}=\pi\times12^2^{} \\ \text{Area}=\pi\times144 \\ \text{Area}=144\pi \end{gathered}[/tex]Hence, the area of the circle in terms of pi is:
[tex]\text{Area}=144\pi ft^2[/tex]OPTION C
