Suppose F = (y +6x,7x + 4z, 6y + 3x) and S is a surface bounded by C, a circle with radius 6, center at (7,0,0), in the plane x = 7, and oriented counterclockwise as viewed from the origin (0,0,0). Find the flux of curl(F) across S and then evaluate the circulation & F. dr. (Use symbolic notation and fractions where needed.) curto curl(F)-dS= F-dr =
