Q:
# A CD tower is shaped like a cylinder and holds CDs with a diameter of 4.75 inches. If the CD tower is 12 inches tall, what is the volume, in cubic inches, that it can hold? Use 3.14 for pi. Round your answer to the nearest hundredth. 212.54 in3 231.56 in3 850.16 in3 867.34 in3

Accepted Solution

A:

For the Volume of a cylinder think of it as a bunch of slices of a circle stacked on top of each other. Therefore the formula is the area of the circle multiplied by the height. The area of a circle is pi(r)^2

(3.14)[.5(4.75)]^2(12)=212.53875

=212.54 in^3

(3.14)[.5(4.75)]^2(12)=212.53875

=212.54 in^3
