Find the volume of a hemisphere whose diameter is 6 cm. (Take π=22/7) |
144π cm3 48π cm3 18π cm3 36π cm3 |
18π cm3 |
We know that, Volume of the hemisphere = \(\frac{ 2}{3}\)π (r)3 Radius (r) = \(\frac{ Diameter}{2}\) = r = \(\frac{ 6}{2}\) = 3 cm Now Volume of the hemisphere = V = \(\frac{ 2}{3}\)π (3)3 = V = \(\frac{ 2}{3}\)π (27) = V = 2 × 9 π = 18π cm3 |
