Question

A gold refinery produces a gold nugget weighing 170 lb.  The density of gold is 19.32 g/cm3.

  • Calculate the volume of the gold nugget in cubic centimeters (cm3).

Volume =  cm3 (give the number written with 4 digits).

  • If the gold is drawn into a wire whose radius is 16 mm, how many feet of gold can be obtained?  The volume of a cylinder is πr2h.  Hint:  you need to solve for h and use the volume calculated in part (a).

Length of wire (or height of cylinder) =  ft (Answer should have 2 significant figures
