Question

A hemispherical bowl has a radius $3.5$ cm. Its volume _______ cm${}^3$.

Answer 1

Radius $=3.5\text{cm}$

Volume of a hemisphere of radius $r$ is $=\frac{2}{3}\pi \times r^3$

$⟹$ Volume $=\frac{2}{3}\times \frac{22}{7}\times 3.5\times 3.5\times 3.5$

$⟹$ Volume $=89.83{\text{cm}}^3$ (approx.)
