Question

find the volume of a sphere of radius 3/2cm​

Answer 1

Radius of sphere = 3/2 cm

$\text{Volume of sphere = } \tt \frac{4}{3} \pi {r}^{3} \\ \\ \frac{4}{3} \times \frac{22}{7} \times {\bigg( \frac{3}{2} \bigg)}^{3} \\ \\ \frac{4}{3} \times \frac{22}{7} \times \frac{27}{8} \\ \\ \frac{4}{3} \times \frac{22}{7} \times \frac{3 \times 9}{4 \times 2} \\ \\ \frac{\cancel4}{\cancel3} \times \frac{\cancel2 \times 11}{7} \times \frac{\cancel3 \times 9}{ \cancel4 \times \cancel2} \\ \\ \frac{99}{7} \: \: \rm {cm}^{3}$
