Question

Find the area and circumference of this circle. Write your answer correct to the nearest hundredth

Answer 1

Explanation:

So we have that the diameter is 30, meaning the radius is 15.

Area:
`A=\pi r^(2)=\pi \cdot 15^(2)=225\pi \approx 706.86`

Circumference:
`C=2\pi r=2\pi \cdot 15 = 30\pi \approx 94.25`
