A capsule is in the shape of a cylinder with two hemisphere stuck to each of its ends. If the length of the entire capsule is 12 mm and the diameter of the capsule is 5 mm, how much medicine it can hold?

Answer»

ANSWER:

the question has been solved step by step below

Step-by-step explanation:

Width of capsule =5mm

radius of HEMISPHERE =2.5mm

c.s.a of hemisphere=2πr SQUARE

=275mm square × 2

=550mm square

height of CYLINDER=14-radis of 2 hemisphere

=9mm

c.s.a of cylinder =2πrh

=131.2mm square

surface area of capsule =c.s.a of 2 hemisphere

+ c.s.a of cylinder

= 682.2mm square

[PIE value=22/7]

the surface area of tablet is 682.2mm square
