6-80.

The height (

*h*) of a cylinder varies directly with the volume (*V*) and inversely with the square of the radius of the base. Homework Help ✎Find an equation for the height in terms of the volume and the radius. Use

*k*to represent the constant of proportionality.When the volume is 20 and the radius is 2, the height is 15. Find the height when the radius is 3 and the volume is 10.
