A capsule of medicine is in the shape of a sphere of diameter 2.8 mm. How much medicine is needed to fill this capsule (correct to one decimal place) ? $\left(\pi =\frac{22}{7}\right)$

$11.5\, mm^3$

A capsule of medicine is in the shape of a sphere of diameter 2.8 mm.

Volume of spherical medicine = 4Πr³/3 = 4Π(2.8)³/3 = 4Π*(21.952)/3 = 11.4986

The correct answer is option (1) : $11.5\, mm^3$
