A solid metallic sphere of diameter 8 cm is melted and drawn into a cylindrical wire of uniform width. If the length of the wire is 12 m, find its width.

Given:Diameter of sphere = 8cm 

Radius of sphere= 8/2=4cm=0.04m

 

Length of wire(cylinder)=12m

Now,

Volume of sphere= Volume of cylindrical wire

4/3 *22/7*4*4*4=22/7 *r2*12

r2=4*4*4*4/3*12

r2=64/9

r=8/3

width =diameter

therefore width =2*8/3=16/3

hence found
