Answer 1

Answer

124.7 ft²

Step-by-step explanation

The area of a circle is calculated as follows:

$A=\frac{\pi D^2}{4}$

where D is the diameter of the circle.

From the diagram, the diameter of the circular top is 12.6 ft, then its area is:

$\begin{gathered} A=\frac{\pi(12.6)^2}{4} \\ A=124.7\text{ ft}^2 \end{gathered}$
