A laboratory experiment requires twelve grams of aluminum wire (d = 2.70 g/cm^3. The diameter of the wire is .200 in. Determine the length of the wire, in centimeters, to be used for the experiment. The volume of a cylinder is (pi)(r)^2(l), where r = radius and l = length.
Update:Correction, the answer is supposed to be 21.9 cm and seeing how you do it would be helpful
