Question

The diameter of hemisphere is 7cm find the volume of hemisphere

Answer 1

Answer:

diameter = 7 cm

$vol = \frac{2}{3} \pi \times {r}^{3} \\ = \frac{2 \times 22 \times 7 \times 7 \times 7}{3 \times 7 \times 2 \times 2 \times 2} \\ = \frac{11 \times 7 \times 7}{3 \times 2} \\ = \frac{77 \times 7}{6} \\ = 89.88 {cm}^{3}$
