Question

the chalk circle around the pitchers mound has a diameter of 16 ft. what is the area of the pitchers circle? $a= ?$ $ft^{2}$

Explanation:

Step1: Find the radius

The radius $r$ is half the diameter.
$r = \frac{16}{2} = 8$ ft

Step2: Apply circle area formula

Use the formula for the area of a circle $A = \pi r^2$.
$A = \pi \times 8^2 = 64\pi$
If using $\pi \approx 3.14$, $A \approx 64 \times 3.14 = 200.96$

Answer:

$64\pi$ ft² (or approximately 200.96 ft²)
