Answer:

Step-by-step explanation:
The below formula can be used to find the area of a circle;

Given A = 144 pi ft^2, let's go ahead and express the equation in terms of r;
![\begin{gathered} 144\pi=\pi* r^2 \\ r^2=(144\pi)/(\pi) \\ r=\sqrt[]{144} \\ r=12ft \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/5i5i9ajve3teviit27zfu56kl99p06pnuf.png)
The below formula can be used to find the circumference of a circle;

Since r = 12ft, let's go ahead and solve for C;
