A solid consisting of right circular cylinder with a hemisphere of one end and a cone and the other. Their common radius is 7 cm. The height of cylinder and cone are each of 4 cm. Find the volume of the solid.
height of cylinder = height of cone = $$4 cm$$
radius of all = $$7 cm$$
To find : volume of the figure
Th collective volume = volume of hemisphere + volume of cylinder + volume of cone
