A solid iron pole consists of a cylinder of height 220 cm and base diameter 24 cm, which is surmounted by another cylinder of height 60 cm and radius 8 cm. Find the mass of the pole, given that `1\ c m^3`of iron has approximately 8g mass.

Text Solution

Verified by Experts

Total Volume of pole=Volume of cylinder 1+ Volume of cylinder 2.
=`pi(r_1)^2(h_1)+pi(r_2)^2(h_2)`
=`pi(12)^2(220)+pi(8*8*60)`
=`22*36520/7`
=114777.14
