Answer:
Length of Capsule (l) = 14 mm
Diameter of Capsule = Diameter of Cylinder =5 mm
Radius = 2Diameter
Therefore, Radius of each Hemisphere = Radius of Cylinder = r = 25 = 2.5 mm
Length of Cylinder = AB = Total length of Capsule - Radius of left Hemisphere - Radius of Right Hemisphere
=14−2.5−2.5=9 mm
Surface Area of Capsule = Curved Surface Area of Cylinder + Surface Area of Left Hemisphere + Surface Area of Right Hemisphere
=2πrl+2πr2+2πr2
=2πrl+4πr2
=2×722×2.5×9+4×722×2.52
=722[45+25]=722×70=220 mm2
