the average shot piece is a cylinder with a diameter of 7.5 mm, a height of 2.0 mm, and a mass of 0.40 g. The average zinc granule is a sphere with a diameter of 0.84 mm. Using the formulas listed below, calculate the total surface area for 0.40 g of each form of zinc. Surface area of a cylinder = 2?r2 + 2?rh          Surface area of a sphere = 4?r2 Volume of a sphere = 4/3?r3                 Volume of cylinder = ?r2h                   Density of zinc = 7.141 g/mL
