a sphere of 6cm is melted and made into wires of length 36cm how to find the radius of the wire

Answer :

volume of sphere = 4/3πr³
                         = (4/3)π6³
                         = (4/3)216π
                         = 288π
volume of wire = πr²h
                     = 36πr²
volume of sphere = volume of wire
288π=36πr²
r²=288/36
r²=8
r=√8
