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
[tex]V = \pi r^2 h[/tex]
Where r is radius and h is height.
Now we can plugin r = 2.35 inch and h = 12 inch
[tex]V = \pi*(2.35)^2 * 12[/tex]
[tex]= \pi * 5.5225 * 12 = 66.27* \pi[/tex]
in genera [tex]\pi = 3.14[/tex]
So [tex]V = 66.27 * 3.14 = 206.0997[/tex] cubic inch
So
