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 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.
