Use a parametrization to express the area of the surface as a double integral. Then evaluate the integral. The portion of the cone 2 = 41/ x2 + y2 between the planes 2 = 4 and 2 =16 Let u = r and v = 8 and use cylindrical coordinates to parametrize the surface. Set up the double integral to nd the surface area. If( )dudv (Type exact answers.) Use a parametrization to express the area of the surface as a double integral. Then evaluate the integral.
