A metallic sphere of radius 12 cm is melted and drawn into a wire, whose radius of cross section is 8 cm. What is the length of the wire?  Choose the correct choice from the following answers: A) 16 cm B) 24 cm C) 28 cm D) 36 cm E) 39 cm

Rationale: "volume of the wire ( in cylindrical shape ) is equal to the volume of the sphere . π ( 8 ) ^ 2 * h = ( 4 / 3 ) π ( 12 ) ^ 3 = > h = 36 cm answer : d"
Answer: D
