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

Respuesta :

18 pi yd2 and 56.5 yd2

As the shape of the pool is circular,

So area of the pool = [tex] \prod \times r^{2} [/tex]

radius = r = 3 yards

Area of the pool = [tex] \prod \times 3^{2} [/tex]

Area of the pool = [tex] \prod \times 9 [/tex]

Area of the pool = [tex] 9\prod [/tex]

So area of two pools of same size = [tex] 2 \times 9\prod [/tex]

Area of two pools of same size = [tex] 18 \prod [/tex]

[tex] \prod [/tex] = 3.14

Area of two pools of same size = [tex] 3.14 \times 18 [/tex]

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

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