Question

Amanda purchased a circular pool cover with a diameter of 30 feet. rounded to the nearest whole number, which pool area would the cover best fit over?

Answer 1

Hi there!

To find the area of a circle, we use the equation A=
`\pi`r^2
Diameter is 2 times the radius. Therefore, r=d/2
r=30/2
r=15
A=
`\pi`15^2
A=225
`\pi`
A=706.858 feet

Hope this helps!
