Find the total surface area of a hemisphere and a solid hemisphere each of radius 10 cm. (π = 3.14). |
|
Answer» Radius of a hemisphere = Radius of a solid hemisphere = 10 cm Surface area of the hemisphere = 2πr2 = 2 x 3.14 x (10)2 cm2 = 628 cm2 And, surface area of solid hemisphere = 3πr2 = 3 x 3.14 x (10)2 cm2 = 942 cm2 |
