Question

2) The inner radius of a metallic tube of density
10 g per cmis 7 cm. The thickness of the tube
is 0.35 cm. Find the weight of the tube if it is of
length 30 cm.​

Answer 1

Answer:

Step-by-step explanation:

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
