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 12mm and the diameter of the capsule is 3mm how much medicine it can hold
Answers
Answer:
pls mark as brainlist answer
Step-by-step explanation:
Given:
Length of Capsule (l) = 14 mm
Diameter of Capsule = Diameter of Cylinder =5 mm
Radius =
2
Diameter
Therefore, Radius of each Hemisphere = Radius of Cylinder = r =
2
5
= 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+2πr

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
