The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height.
Given that the volume of the cone is 18π cubic feet and the height is 6 ft, we can plug in these values to solve for the radius:
18π = (1/3)πr^2(6)
18 = 2r^2
r^2 = 9
r = 3
Therefore, the radius of the cone is 3 ft.
