A metallic sphere of radius 12 cm is melted and drawn into a wire, whose radius of cross section is 12 cm. What is the length of the wire?  Choose the most appropriate option:
A) 6 cm  B) 14 cm  C) 16 cm  D) 23 cm  E) 29 cm

Rationale: "volume of the wire ( in cylindrical shape ) is equal to the volume of the sphere . π ( 12 ) ^ 2 * h = ( 4 / 3 ) π ( 12 ) ^ 3 = > h = 16 cm answer : c"
Answer: C
