Question

Megan wants to buy a solar blanket for her circular pool. The blanket sits on top of the water to keep it warm if the diameter of the pool is 18 feet how many square feet of the water will the blanket cover?

Answer 1

Answer:

254.5 ft²

Step-by-step explanation:

First, find the area of the surface of the pool:

a = πr², r is half of the diameter → 18 ÷ 2 = 9

a = π × 9² - this can be simplified

a = 81π = 254.469... ≈ 254.5 ft²

Hope this helps!
