Question

A capsule of medicine is in the shape of a sphere of diameter 3.5 mm. How much medicine (in mm³) is needed to fill this capsule?

`["Assume "pi=22/7]`

 

Answer 1

Radius (r) of capsule = `(3.5/2)  mm` = 1.75 mm

Volume of the spherical capsule = `4/3pir^3`

= `[4/3xx22/7xx(1.75)^3]mm^3`

= 22.458 mm³

= 22.46 mm³      (approximately)

Therefore, the volume of the spherical capsule is 22.46 mm³.
