A solid consisting of a right circular cone of height 120 cm and radius 60 cm standing on a hemisphere of radius 60 cm is placed upright in a right circular cylinder full of water such that it touches the bottom. Find the volume of water left in the cylinder, if the radius of the cylinder is 60 cm and its height is 180 cm.
Solution:
Radius of hemisphere = Radius of Cone = Radius of Cylinder = r = 60 cm
Height of Cone = h =120 cm
Height of Cylinder
cm
Volume of solid = Volume of hemisphere + Volume of Cone
Volume of Water initially present in the cylinder = Volume of Cylinder
Volume of Water left in the cylinder = Volume of Water initially present in the cylinder-Volume of solid
