Answer
124.7 ft²
Step-by-step explanation
The area of a circle is calculated as follows:
[tex]A=\frac{\pi D^2}{4}[/tex]
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:
[tex]\begin{gathered} A=\frac{\pi(12.6)^2}{4} \\ A=124.7\text{ ft}^2 \end{gathered}[/tex]
