The area of the circle is \(100\pi\) square feet.
Explicar
## Step 1<br />The circumference of a circle is given by the formula \(C = 2\pi r\), where \(r\) is the radius of the circle.<br /><br />## Step 2<br />Given that the circumference \(C = 20\pi\), we can set up the equation \(2\pi r = 20\pi\) to solve for \(r\).<br /><br />## Step 3<br />Solving for \(r\), we get \(r = 10\).<br /><br />## Step 4<br />The area of a circle is given by the formula \(A = \pi r^2\).<br /><br />## Step 5<br />Substituting \(r = 10\) into the area formula, we get \(A = \pi (10)^2 = 100\pi\).
