<span>Diameter of the sphere = 8 cm.
Therefore, the radius of the sphere = 8/2 = 4 cm
Volume of the sphere = 4/3 * 22/7 * 3 * 3 * 3 cu. cm.
The sphere is beaten and drawn into a wire, the wire is cylinder of the diameter = 0.2 cm
Area of the base of the cylinder = pi * r2 = 22/7 * 0.2 * 0.2 sq. cm
volume of the wire = pi * r2 * I = 22/7 * 0.2 * 0.2 * 1
Therefore, 22/7 * 0.2 * 0.2 * I = 4/3 * 22/7 * 4 * 4 * 4
Therefore I = 4/3 * 22/7 * 4 * 4 * 4 * 7/22 * 1/0.04
I = 256/3 * 1/0.04
I = 2113 cm</span>
