please solve the following questions:

4. Consider the integral So So S,2 xyzdadydz. Rewrite this integral in the order dadzdy and dzdydx. Eval- uate one of these. 5. Consider the surface parametrization(v), usin(v), uv) where u goes from 0 to 27 and v goes from 0 to 47. Finf the surface area. 6. Let F(x, y, z) = (-y, x, xyz). Let S be part of the sphere x2 + y2 + 22 = 25 that lies below the plane z = 4. Calculate SSs curlF . ds
