Question

the diameter of a circle is 6 miles. what is the circles area?
round your answer to the nearest hundredth.
______ square miles

Explanation:

Step1: Find radius from diameter

Radius $r = \frac{d}{2} = \frac{6}{2} = 3$ miles

Step2: Apply circle area formula

Area $A = \pi r^2 = \pi \times 3^2 = 9\pi$

Step3: Calculate and round to hundredth

$9\pi \approx 9 \times 3.1416 = 28.2744 \approx 28.27$

Answer:

28.27 square miles
