A medicine capsule is in the shape of a cylinder of diameter 0.5 cm with two hemisphere struck to each of its ends. The length of the entire capsule is 2 cm. The capacity of the capsule is

Given: A cylinder of diameter 0.5 cm


The length of the entire capsule is 2 cm


Here, Radius of the Cylinder and Hemisphere is = 0.25cm


Height of the Cylinder = length of capsule – 2 × (radius of hemisphere) = 2 – 0.5 = 1.5cm


Volume of Cylinder is: πr2h (here r, h are radius and height of the cylinder respectively)


Volume of hemisphere is: πr3 (here r is the radius of the hemisphere)


Let V1 be the Cylindrical part of the capsule


V1 = πr2h = π × (0.25)2 × (1.5) = 0.09375π cm3


Let V2 be the Cylindrical part of the capsule


V1 = πr3 = π(0.25)3 = π cm3


Volume of the capsule = V1 + 2V2 = 0.09375π + 2 × π = 0.3599 0.36cm3


Volume of the capsule is 0.36cm3
