Question

A capsule of medicine is in the shape of a sphere of a diameter $3.5m{m}^3$ is needed to fill this capsule?

Answer 1

Given:

Radius $=\frac{3.5}{2}=1.75$

$\Rightarrow$Volume $=\frac{4}{3}\times \pi \times {\left(r\right)}^3$

$\Rightarrow$Volume $=\frac{4}{3}\times \frac{22}{7}\times {\left(1.75\right)}^3$

$=22.46$mm${}^3$
