Question

What is the area of the circular Olympic wrestling arena if it has a diameter of 29.5 feet?

Answer 1

Since the Olympic wrestling arena has a circular shape, we can find the area using the following formula:

$\begin{gathered} A=\pi r^2 \\ \end{gathered}$

Where:

$r=\frac{diameter}{2}=\frac{29.5}{2}=14.75ft$

Therefore:

$\begin{gathered} A=\pi(14.75)^2 \\ A\approx683.49ft^2 \end{gathered}$

Answer:

683.49 ft²
