A bead is made from material with constant density 7 grams per cubic millimeter by drilling a cylindrical hole of radius 2 mm through a sphere of radius 7 mm. a. Set up a triple integral in cylindrical coordinates representing the mass of the bead in grams (do not include units).
b. Find the mass of the bead.
