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) 9
B) 8
C) 7
D) 6
E) 5
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   9nswer:9
