Question

PLEASE HELP!

Find the height of the cylinder below whose volume is approximately thousand cubic inches. Use 3.14 for pi. Round your answer to the nearest hundredth. Show your work.

d=9in

Answer 1

≈ 15.73 in

Explanation:

Since the volume of a cylinder is
`\pi r^(2)`
`h`, we can set the equation,

`\pi r^(2)`
`h` = 1000

Since the radius of the circle is 4.5, we square it to get

`20.25 \pi`
`h`= 1000

Dividing by 20.25 on both sides, we get

`\pi h` ≈ 49.38

Dividing by 3.14 on both sides, we get

`h` ≈ 15.73 in
