Given:

The radius , r=20 ft.

The height , h=23 ft.

The volume of the cylinder can be calculated as,

[tex]\begin{gathered} V=\pi r^2h \\ =\pi\times20^2\times23 \\ =28902.65ft^2 \end{gathered}[/tex]

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

The volume of the cone can be calculated as,

[tex]\begin{gathered} V=\frac{1}{3}\pi\times r^2h \\ =\frac{1}{3}\pi\times20^2\times23 \\ =9634.22ft^2 \end{gathered}[/tex]

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