Question

A fountain in the park has two circular pools that are the same size. What is the total area of the pools if the radius is 3 yards? Use 3.14 for pi and round the approximate area to the nearest tenth, if necessary.Check all that apply.

9 pi yd2
12 pi yd2
18 pi yd2
28.3 yd2
56.5 yd2

Answer 1

18 pi yd2 and 56.5 yd2

Answer 2

As the shape of the pool is circular,

So area of the pool =
`\prod * r^(2)`

radius = r = 3 yards

Area of the pool =
`\prod * 3^(2)`

Area of the pool =
`\prod * 9`

Area of the pool =
`9\prod`

So area of two pools of same size =
`2 * 9\prod`

Area of two pools of same size =
`18 \prod`

`\prod` = 3.14

Area of two pools of same size =
`3.14 * 18`

Area of two pools of same size = 56.52 sq. yd

Area of two pools of same size = 56.5 sq. yd
