1. A solid is in the shape of a cone standing on a hemisphere with both their radii being equal to 1 cm and the height of the cone is equal to its radius. Find the volume of solid in terms of .
Radius of Hemisphere = Radius of Cone = r = 1 cm
Height of Cone = h = Radius of Cone = 1 cm
Volume of Solid = Volume of Hemisphere + Volume of Cone
