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
