Q3 of 44 Page 14

A medicine capsule is in the shape of a cylinder with two hemispheres stuck to each of its ends. The length of the entire capsule is 14 mm, and the diameter of the capsule is 5 mm. Find its surface area.


Given:


Diameter of cylinder = 5mm


The radius of cylinder


Height of cylinder = 14 – 5 = 9mm


Here, Diameter of hemisphere =. 5mm


So,


The total area of the capsule = CSA of cylinder + CSA of 2 hemispheres


= 2πrh + 2×2πr2




=220 mm2
