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 = $\prod \times r^{2}$

radius = r = 3 yards

Area of the pool = $\prod \times 3^{2}$

Area of the pool = $\prod \times 9$

Area of the pool = $9\prod$

So area of two pools of same size = $2 \times 9\prod$

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

$\prod$ = 3.14

Area of two pools of same size = $3.14 \times 18$

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

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