The diameter of a sphere is 6 cm. It is melted and drawn into a wire of diameter 2 mm. Find the length of the wire.

Given,


Diameter sphere = 6cm


r = 3cm


radius of wire =


r = 0.1cm


let us consider length of wire = h cm


When we convert any object into another shape the volume will remain same.


Volume of sphere = volume of cylinder





h = 36 × 100 =3600


h = 36m
