Question

Cd tower is shaped like a cylinder and holds CDs in a diameter of 4.7 inches . If the cd tower is 12 inches tall what is the volume in cubic inches. Use 3.14 for pi. Round your answer to the nearest hundredth

Answer 1

CD tower is a cylinder in shape.
Height of CD tower is = 12 inch
Diameter of CD which CD tower holds is = 4.7 inch
So we can say radius of CD is = 4.7/2 = 2.35 inch

So we can say it is cylinder in shape having height = 12 inch and radius = 2.35 inch.

In general volume of cylinder is

`V = \pi r^2 h`
Where r is radius and h is height.
Now we can plugin r = 2.35 inch and h = 12 inch


`V = \pi*(2.35)^2 * 12`

`= \pi * 5.5225 * 12 = 66.27* \pi`
in genera
`\pi = 3.14`
So
`V = 66.27 * 3.14 = 206.0997` cubic inch
So
