1.	A capsule of medicine is in the shape of a sphere of diameter 3.5 mm. How much medicine (in mm3) is needed to full this capsule ?
Answer» Volume of a hemisphere = \(\frac{4}{3}\)πr³ Given, capsule of medicine is in the shape of a sphere of diameter 3.5 mm. Radius = \(\frac{3.5}{2}\) = 1.75 mm Volume of medicine filled inside = \(\frac{4}{3}\) × π × 1.75³ = 22.458 mm³

Answer»

Volume of a hemisphere = \(\frac{4}{3}\)πr³

Given,

capsule of medicine is in the shape of a sphere of diameter 3.5 mm.

Radius = \(\frac{3.5}{2}\) = 1.75 mm

Volume of medicine filled inside = \(\frac{4}{3}\) × π × 1.75³

= 22.458 mm³
