Answer:
22.46 mm³ medicine is needed to fill in this capsule.
Step-by-step explanation:
We know that,
Capsule is in form of sphere.
Radius of sphere = r = d/2 = 3.5/2 = 1.75 mm
Medicine needed to fill = Volume of sphere
=> 4/3 πr³
=> [4/3 × 22/7 × (1.75)³]
=> [4/3 × 22/7 × 1.75 × 1.75 × 1.75]
=> 22.46 mm³
Hence, Medicine need to fill this capsule would be 22.46 mm³.
