Question

the chalk circle around the pitchers mound has a diameter of 16 ft
what is the area of the pitchers circle?
a =? ft²

Explanation:

Step1: Find the radius

The diameter \( d = 16 \) ft, and the radius \( r=\frac{d}{2}\). So \( r=\frac{16}{2}=8 \) ft.

Step2: Calculate the area

The formula for the area of a circle is \( A = \pi r^{2} \). Substitute \( r = 8 \) into the formula: \( A=\pi\times8^{2}=\pi\times64 = 64\pi\approx 200.96 \) \( \text{ft}^2 \) (using \( \pi\approx3.14 \)).

Answer:

\( 200.96 \) (or \( 64\pi \))
