Answer 1

Explanation:

The circumference is the perimeter of a circle, which is equal to 131.88ft.

Circumference =
`2\pi r^(2)`

`131.88=2\pi r^(2) \\r^(2) =(131.88)/(2\pi ) \\r=√(20.989) \\r=4.581`

This means that the diameter is:

`d=2r\\d=9.163`

So our area is:

`A=\pi r^(2) \\A=\pi (4.581)^(2) \\A=65.940`

Hope this helped!
