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 correct choice from the following:  A) 6 cm  B) 14 cm  C) 16 cm  D) 23 cm  E) 29 cm
Volume of the wire (in Cylindrical shape) is equal to the volume of the sphere.   π(12)^2 * h = (4/3)π (12)^3 =&gt; h   = 16 cm   Answer:16 cm
