In this question, you may find the following helpful. For a hemisphere of radius r, its volume is given by ³ and its curved surface area is given by 2². 10 r cm Figure 2 h cm Figure 2 shows a solid which is made up of a cylinder with radius r cm and height h cm. A hemisphere of radius r cm is attached at one end of the cylinder. The total surface area of the solid is 980 cm². Express h in terms of r and hence show that the volume of the solid, V, is given by 5 V = 490r-r³
