A metallic sphere of radius 12 cm is melted and drawn into a wire, whose radius of cross section is 24 cm. What is the length of the wire?
Pick one
A) 6 cm
B) 4 cm
C) 8 cm
D) 3 cm
E) 9 cm
Volume of the wire (in Cylindrical shape) is equal to the volume of the sphere.   π(24)^2 * h = (4/3)π (12)^3 =&gt; h   = 4 cm   Answer:4 cm
