A right circular cylinder of radius 7cm, Just encloses a sphere. Find the ratio of volume of cylinder to that of the sphere....
r = 7cm
h = 2r = 2*7cm
volume of cylinder = πr2h = 686π
volume of sphere = 4/3 πr3 = 343* 4/3 π
volume (cylinder) / volume (sphere) = 3:2
h = 2r = 2*7cm
volume of cylinder = πr2h = 686π
volume of sphere = 4/3 πr3 = 343* 4/3 π
volume (cylinder) / volume (sphere) = 3:2
