Question

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

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given parameters

`\begin{gathered} r=12ft,\pi=\pi \\ \text{Area}=\pi r^2 \end{gathered}`

STEP 2: Calculate the area of the given circle of radius 12ft

`\begin{gathered} \text{Area}=\pi r^2 \\ By\text{ substitution,} \\ \text{Area}=\pi*12^2^{} \\ \text{Area}=\pi*144 \\ \text{Area}=144\pi \end{gathered}`

Hence, the area of the circle in terms of pi is:

`\text{Area}=144\pi ft^2`
