12) The inner radius of a metallic tube of density 10 g per cm is 7 cm. The thickness of the tube is 0.35 cm. Find the weight of the tube if it is of length 30 cm.
Answers
Answer:
volume of total cylinder = 3.14*1.54*1.54*30
= 223.404
volume of the hollow space of the cylinder = 3.14*1.25*1.25*30
=147.187
subtracting both of them = 223.404 - 147.187
= 76.217
Density of the cylinder = 76.217*7
= 533.519 gm/cm cube
