Question

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



I need answer with steps.....​

Answer 1

Step-by-step explanation:

given

length of a capsule(1)=14mm

diameter of a capsule= diameter of a cylinder =5mm

radius=diameter/2

therefore radius of each hemisphere= radius of cylinder=r=5/2=2.5mm

length of cylinder =AB= total length of capsule - radius of left hemisphere - radius of right hemisphere

=14-2.5-2.5

=9mm

surface area of capsule = curved surface area of cylinder + surface area of left hemisphere + surface area of right hemisphere

=2πrl+2πr^2+2πr^2

=2πrl+4πr^2

=2×22/7×2.5×9+4×22/7×2.5^2

=22/7(45+25)=22/7×70

=220mm^2

hope help you
