Question

What is the circumference and area in feet of circular pool that has a diameter of 20 yards?

Answer 1

`188.50 ft.` and `2,827.43ft.^2`

Explanation:

`diameter=2r=20` => `r=10yards`
`1 yd.=3 ft.`
`10yds.=30 ft.`

`Perimeter_circ=2pi*r=2pi*(30)=60pi ft.~=188.50 ft.`

`Area_circ=pi*r^2=pi*(30)^2=900pi ft.^2~=2,827.43 ft.^2`
