2.1. Set up, but do not evaluate, a double integral representing the surface area of the portion of the paraboloid z = 16 - x^2 - 4y^2 in the first octant.
2. Evaluate the triple integral. (from left to right, top numbers are 9, y/3, and sqrt(y^2 - 9x^2), bottom numbers are all zero) z dz dx dy
(both are from Calculus Early Transcendental Functions 5e) 14.5 #16 and 14.6 #4
3. Find the volume of the solid bounded by the surface z = 25 - x^2 - y^2 and the plane z = 0
