Question

14.A sphere and a right circular cylinder have the same radius. If the volume of the sphere is

five times the volume of the cylinder, then what is the ratio of cylinder's height and

radius?

Answer 1

let radius be r
4/ 3*πr^3=πr^2h
dividing by πr^2,
4/3r=h,
therefore, I h:r=4/3:1

Answer 2

let r be the radius of sphere and right circular cylinder.
volume of cylinder = πr^2h
where h be the height of cylinder
volume of a sphere = 4
