A metallic sphere of radius 12 cm is melted and drawn into a wire, whose radius of cross section is 16 cm. What is the length of the wire? Choose the correct choice from the following answers:	A) 1 cm	B) 6 cm	C) 2 cm	D) 5 cm	E) 9 cm
Volume of the wire (in Cylindrical shape) is equal to the volume of the sphere.   π(16)2 * h = (4/3)π (12)3   =&gt; h = 9 cm   Answer:9 cm
