Question

The volume of a tree stump can be modeled by considering it as a right cylinder.

Bentley measures its height as o.9 ft and its volume as 3304 cubic inches. Find the stump's diameter in inches. Round your answer to the nearest tenth if necessary.

Answer 1

19.7

Explanation:

volume = area of the base times the height

v =
`\pi r^(2) h`

.9 feet is 10.8 inches

r =
`\sqrt{(3304)/(\pi (10.8)) }`

r ≈ 9.86809235172

d = 2r

d ≈ 19.7361847034

Rounded is 19.7
