The wire is in the shape of a cylinder.
Since the sphere is melted and a cylindrical wire is formed, their volumes are equal.
Volume of a sphere =

As the diameter of the sphere is 6 cm, its radius r=3 cm
Volume of a Cylinder =πR

h
Length of the wire h=36m=3600cm
Hence, Volume of sphere = Volume of the wire
