Hope it helps !!

NOW,

wire is cylindrical

v=pie r sq. h=>3.14*1/10*/10*3600=113.04

v of the cylinder(wire) is

YOU KNOW V. OF WIRE=V. OF SPHERE

and

v of the sphere will be

so,,, v of sphere=2/3 pie r cube

pie r cube=113.04*3/2

r cube=113.04*3/2/3.14

r cube=54.00

r=cube root of 54=>3.77

<> >r of sphere=
