Explanation
Step 1
the area of a circle is given by:
[tex]\text{Area}_{circle}=\text{ }\pi\cdot\frac{diameter^2}{4}[/tex]let
diameter=16 ft
now, replace
[tex]\begin{gathered} \text{Area}_{circle}=\text{ }\pi\cdot\frac{diameter^2}{4} \\ \text{Area}_{circle}=\text{ }\pi\cdot\frac{(16ft)^2}{4} \\ \text{Area}_{circle}=\text{ }\pi\cdot\frac{256ft^2}{4} \\ \text{Area}_{circle}=201.06ft^2 \end{gathered}[/tex]I hope this helps you
