the volume of a cone varies jointly as its height and the square of its radius. A cone with a radius of 6 inches and a height of 10 inches has a volume of 120pi cubic inches. Find the volume of a cone having a radius 18 inches and a height of 20 inches.

The formula for the volume of a cone is: \({r^2 \pi h } \over 3\)

Plugging in the values, we have: \({18^2 \pi 20 \over3} = \color{brown}\boxed{2160 \pi}\)
