# 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? - Mathematics

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]

#### Solution

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

"Volume of 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.
