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?
Answers
Given : Diameter of capsule of medicine (sphere) = 3.5 mm
Radius of capsule of medicine (sphere) = 3.5/2 = 1.75 mm
Volume of sphere = 4/3 πr³
Volume of medicine needed to fill this capsule ,V = (4/3) × π × 1.75³
V = (4/3) × 22/7 × 1.75 × 1.75 × 1.75
V = 4/3 × 22 × 0.25 × 1.75 × 1.75
V = 67.375/3
V = 22.458 mm³
Hence, 22.458 mm³ medicine needed to fill this capsule.
