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
Volume of the wire (in Cylindrical shape) is equal to the volume of the sphere.   π(8)^2 * h = (4/3)π (12)^3 =&gt; h   = 36 cm   Answer:36 cm
