The metal to be used for covering a cylinder having an external
radius of 5 cm, height 21 cm, and thickness of 1 cm is to be cast
from a cylinder. What should be the height of the cylinder
of radius 3 cm from which this casting can be done?
Volume of metal to be casted = (22/7) × [(5)2 – (4)2] × 21
So (22/7) × 32 × h = (22/7) × [(5)2 – (4)2] × 21
Solve, h = 21
