(10 points) Find the mass of the solid inside the sphere x 2 + y 2 + z 2 = 9 and above the cone z = p x 2 + y 2 , if the density is ( x,y,z ) = z 2 . mass = 7. (15 points) Apply Greens Theorem to evaluate H C ( x 2 cos x + 2 y ) dx +( y 3 + 5 x ) dy where C is the triangle with vertices (0 , 0), (1 , 0) and (0 , 2), traversed in the counterclockwise direction. H C ( x 2 cos x + 2 y ) dx +( y 3 + 5 x ) dy = 5 8. (15 points) Let S be the cylindrical region x 2 + y 2 4, 0 z 3, and let n be the outward unit normal to the boundary S of S . If F ( x,y,z ) = ( x 3 z + y 2 ) i + ( x 2 + y 3 z ) j + ( x 2 + y ) k , nd the ux of F across S . ux = 6...
