Question

The volume of a cylinder is 54\pi cubic inches and the height is 6 inches. Find the radius.

Answer 1

radius = 3 inches

Explanation:

Volume of a circular cylinder is given by the formula

V = π r ² h
where
V = volume

r = radius

h = height

Given V = 54π and h = 6 we get

54π = π · r² · 6 = 6πr²

r² = 54π/6π

r² = 9

r = √9

r = 3
