A cylindrical tube, open at both ends, is made of metal. The internal diameter of the tube is 10.4cm and its length is 25cm. The thickness of the metal is 8mm everywhere. Calculate the volume of the metal.

Text Solution

Verified by Experts

Internal radius =`5.2 cm`
External radius =`(5.2+0.8) cm`=`6cm`
Also,`h=25cm`.
Therefore,Volume of metal =`pi(R^2-r^2)xxh`
=`704 cm^3`
