Question

the diameter of a circle is 18 yards. what is the circles area?
round your answer to the nearest hundredth.
______ square yards

Explanation:

Step1: Find radius from diameter

$r = \frac{d}{2} = \frac{18}{2} = 9$ yards

Step2: Apply circle area formula

$A = \pi r^2 = \pi \times 9^2 = 81\pi$

Step3: Calculate and round to hundredth

$81\pi \approx 81 \times 3.14159 \approx 254.47$

Answer:

254.47 square yards
