Question

the diameter of a circle is 8 yards. what is the circles area? round your answer to the nearest hundredth.

Explanation:

Step1: Find radius from diameter

$r = \frac{d}{2} = \frac{8}{2} = 4$ yards

Step2: Apply circle area formula

$A = \pi r^2 = \pi (4)^2 = 16\pi$

Step3: Calculate and round result

$16\pi \approx 16 \times 3.1416 = 50.2656 \approx 50.27$ square yards

Answer:

50.27 square yards
