Question

Find the volume of a cylinder and cinema given the following dimensions

Answer 1

Given:

The radius , r=20 ft.

The height , h=23 ft.

The volume of the cylinder can be calculated as,

`\begin{gathered} V=\pi r^2h \\ =\pi*20^2*23 \\ =28902.65ft^2 \end{gathered}`

Therefore, the volume of the cylinder is 28902.65 sq.ft.

The volume of the cone can be calculated as,

`\begin{gathered} V=(1)/(3)\pi* r^2h \\ =(1)/(3)\pi*20^2*23 \\ =9634.22ft^2 \end{gathered}`

Therefore, the volume of the cone is 9634.22 sq.ft.
