Question

An above-ground swimming 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 the water in the pool?⇆

Answer 1

the correct answer is the V = 1144.53

Explanation:

This is the answer because you use the formula V = π*r^2*h

And you get 1144.53

Answer 2

The volume of a cylinder is

(pi) (radius²) (height) .

Radius = 1/2 diameter.
Radius of this pool = (1/2) (18 ft) = 9 ft

The pool is a cylinder with height of 4.5 feet.
The water in it is also a cylinder, but only 4 ft high.

Volume of the water =

(pi) x (radius²) x (height)

= (pi) x (9 ft)² x (4 ft)

= (pi) x (81 ft²) x (4 ft)

= (pi) x (324 ft³) = 1,017.9 ft³ .
