Further Volume and Surface Area

The hemisphere must also have radius 5 cm. Volume of the hemisphere = volume of sphere = = = 262 cm3. Therefore total volume of the object = 1728 + 262 = 1990 cm3. Problem style example. A tank measures 15 cm by 10 cm by 10 cm. The tank is half-full of water. A solid metal sphere with radius 2 cm is placed into the tank. ................
