Question

the diameter of a circle is 32 kilometers. what is the circles area? round your answer to the nearest hundredth. square kilometers

Explanation:

Step1: Calculate the circle's radius

Radius $r = \frac{d}{2} = \frac{32}{2} = 16$ km

Step2: Apply circle area formula

Area $A = \pi r^2 = \pi \times 16^2$

Step3: Compute and round the result

$A = 256\pi \approx 256 \times 3.1416 = 804.2496 \approx 804.25$

Answer:

804.25 square kilometers
