Answer:
103.87 ft.
In this case, area equals
![\pi r^2](https://img.qammunity.org/2023/formulas/mathematics/college/ptr0qrr4mhrdlntiy0x3rg3tx93ixeolww.png)
The diameter is
![2r](https://img.qammunity.org/2023/formulas/mathematics/high-school/t0alkwbxgfcdelgxv7al7ablovwikdoq2u.png)
But before worrying about anything else, we must start the problem. Let's do that now.
The first step is to find the broken-down form of the area.
A =
![(1)/(4) \pi d^2](https://img.qammunity.org/2023/formulas/mathematics/college/2ky5t1wd0fwz9bxpkrflobhi87869rco2g.png)
Next, break this equation into a solvable definition.
![(1)/(4) * \pi * 11.5](https://img.qammunity.org/2023/formulas/mathematics/college/upavxbzuejt0odnlvu230lhep8dnhe42ob.png)
Lastly, solve this equation, and round.
≈
