Explanation:

Step1: Find radius from diameter

The radius $r$ is half the diameter.
$r = \frac{28}{2} = 14$ yards

Step2: Apply circle area formula

Use the area formula $A = \pi r^2$.
$A = \pi \times 14^2 = 196\pi$

Step3: Calculate and round to hundredth

Compute the numerical value and round.
$A \approx 196 \times 3.1416 = 615.75216 \approx 615.75$

Answer:

615.75 square yards
