thanks in advance

1. Calculate the line integral of the vector field F = (y, x, x2 + y ) around the boundary curve, the curl of the vector field, and the surface integral of the curl of the vector field. The surface S is the upper hemisphere x2 + 12 + z2 = 49, z 20 oriented with an upward-pointing normal. 2. Calculate the line integral of the vector field F = (yz, 0, x) around the boundary curve, the curl of the vector field, and the surface integral of the curl of the vector field. The surface S is the portion of the plane a X + +z =1 where x, y, z 2 0, oriented with an upward-pointing normal
