A capsule of medicine is in the shape of a sphere of diameter 3.5mm. How much medicine (in mm3) is needed to fill this capsule? (Assume π = 22/7)

Given

Diameter of capsule = 3.5 mm

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

Find out

We have to find out how much medicine (in mm3) is needed to fill this capsule

Solution

the volume of spherical capsule = 4/3 πr3

= (4/3)×(22/7)×(1.75)

= 22.458 mm3

Answer

Therefore,22.46 mmmedicine is needed to fill the capsule
