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 yar

mihalych1998 [28]

Answer:

56.6 square yards.

Step-by-step explanation:

Given:

A fountain in the park has two circular pools that are the same size.

<u>Question asked:</u>

What is the total area of the pools if the radius is 3 yards ?

<u>Solution:</u>

First of all we will calculate the area of a circular pool.

As we know:

$Area\ of\ circle=\pi r^{2}$

$=\frac{22}{7} \times(3)^{2} \\ \\ =\frac{22}{7}\times9\\ \\ =\frac{198}{7} \\ \\ =28.28\ square\ yards$

Area of circular pool nearest tenth = 28.3 square yards

Now, as given that both pools are of same size.

Total area of the pools = 28.3 square yards + 28.3 square yards

= 56.6 square yards.

Thus, the total area of the pools are 56.6 square yards.
