Find 1/12th of the volume of a hemisphere whose radius radius is 4.2 m. |
6.6 m³ 7.3 m³ 8.2 m³ 7.1 m³ |
7.3 m³ |
Volume of a hemisphere = $\frac{2}{3} \pi r^3$ radius = 4.2 Volume = $\frac{2}{3} \pi 4.2^3$ = $\frac{2}{3} \frac{22}{7} 4.2 \times 4.2 \times 4.2$ = 2 x 22 x 0.2 x 4.2 x 4.2 = 155.232 m³ 1/12th of the volume = $\frac{1}{12}$ x 155.232 = 7.3 m³ |
