An above ground pool in the shape of a cylinder has a diameter of 18 feet and a height of 4.5 feet. If the pool is filled with water to 6 inches from the top of the pool, what is the volume, to the nearest cubic foot, of water in the pool?

Step1 : Convert 6 inches to foot:

6 inches = 6 : 12 = 0.5 feet

Step 2: Find the height of the water:

Height of the water = 4.5 - 0.5 = 4 feet

Step 3: Find the radius of the cylinder:

Radius = Diameter : 2 = 18 : 2 = 9 feet

Step 4: Find volume of water:

Volume = πr²h = π (9) ² (4) = 1018 ft³ (Nearest cubic foot)

Answer: Volume = 1018 ft³

The volume of 6-inch water is approxmately127.23 ft³:

V=πr²h

V = (3.14) (9) ² (4.5) - (3.14) (9) ² (6inch*1ft/12inch)

V=127.23 ft³
