Answer: We have to find the area and the circumference of the circular flower bed, which has 12 feet diameter:
The formula for the circumference and diameter is:
[tex]\begin{gathered} C=\pi d\rightarrow(1) \\ \\ A=\pi(\frac{d}{2})^2\rightarrow(2) \end{gathered}[/tex]
Using (1) and (2) the answers are determined as follows:
[tex]\begin{gathered} C=\pi d=\pi12ft \\ \\ C=12ft \\ \\ ---------- \\ \\ A=\pi(\frac{d}{2})^2=\pi(\frac{12ft}{2})^2=\pi(6ft)^2 \\ \\ A=36\pi ft^2 \end{gathered}[/tex]
Therefore the answer is the third option.
