Question

Quizplus · Accepted Answer

The area of a circle is given by the formula $A = \pi r^2$, where $A$ is the area and $r$ is the radius. To find the radius, we rearrange the formula to solve for $r$: $r = \sqrt{\frac{A}{\pi}}$. Plugging in the given area of 53 square feet, we get $r = \sqrt{\frac{53}{\pi}}$, which approximately equals 4.1 feet when rounded to the nearest tenth.
