A solid consists of a right circular cone of radius x and height 2x standing on a hemisphere of radius x (take π = 22/7)
The solid is placed upright in a right circular cylinder full of water such that it touches the bottom. If the internal radius of cylinder is x and height is 3x, what is the approximate volume of water left in the cylinder ?
