A piece of ductile metal is in the form of a cylinder of diameter 1 cm and length 5 cm. It is drawnout into a wire of diameter 1 mm. What will be the length of the wire so formed?

Given,


Diameter of metallic cylinder = 1 cm


Radius of cylinder =


Length of cylinder = 5 cm


Diameter of wire drawn from it = 1 mm = 0.1 cm


Let length of wire = h cm


so,


Length of wire drawn from metal =
