# A capsule of medicine is in the shape of a sphere of diameter 3.5 mm. How much medicine (in $${mm}^3$$) is needed to fill this capsule?

Given :
Radius (r) of capsule = $$\frac{3.5}{2} mm = 1.75 mm$$

We know that,

Volume of spherical capsule
= $$\frac{4}{3}{\pi}{r}^3$$
= $$\frac{4}{3} × \frac{22}{7} × {1.75}^3$$ $${mm}^3$$
= $$22.458$$ $${mm}^3$$
= $$22.46$$ $${mm}^3$$(appro×.)

Therefore ,the volume of the spherical capsule is $$22.46$$ $${mm}^3$$.
