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
