What is the total surface area and the curved surface area of a solid hemisphere of radius 14 cm? |
5544 cm2, 1848 cm2 1848 cm2, 1232 cm2 924 cm2, 616 cm2 2772 cm2, 1848 cm2 |
1848 cm2, 1232 cm2 |
We know that, The total surface area of a solid hemisphere = 3πr2 The curved surface area of a solid hemisphere = 2πr2 We have, Radius of hemisphere = 14 cm The total surface area of a solid hemisphere = 3 × \(\frac{22}{7}\) × 142 = 1848 cm2 The curved surface area of a solid hemisphere = 2 × \(\frac{22}{7}\) × 142 = 1232 cm2 |
