The total surface area of a solid hemisphere is 16632 cm2 . Its volume is: (Take π=22/7) |
145232 cm3 140232 cm3 150032 cm3 155232 cm3 |
155232 cm3 |
We know that, Total surface area = 3πr2 We have, TSA of Hemisphere = 16632 cm2 Volume of solid hemisphere = \(\frac{2}{3}\)πr3 So, = 3 × π × r2 = 16632 = r2 = 5544 × \(\frac{7}{22}\) = r2 = 1764 = r = 42 cm Volume = \(\frac{2}{3}\) πr3 = \(\frac{2}{3}\) × \(\frac{22}{7}\) × 423 = 155232 cm3 |
