The volume of a right circular cylinder is 345 cm cube. Then the volume of a right circular cone whose radius of the base and height is same as of circular cylinder,will be?

Let radius of base of cylinder = rheight of cylinder = hNow, volume of cylinder = 345 cm3πr2h =  345  .....1Now, radius of base of cone = radius of base of cylinder = rheight of cone = height of cylinder = hVolume of cone = 13πr2h = 13×345 = 115 cm3
