K Use Green's Theorem to find the counterclockwise circulation and outward flux for the field F = (7y -9x ) i+ (9x + 7y ) j and curve C: the triangle bounded by y = 0, x = 3, and y = x. . . . The flux is (Simplify your answer.) The circulation is. (Simplify your answer.)Use the Green's Theorem area formula, Area of R = - Ox dy - y dx, to find the area of the region, R, enclosed by the astroid, r(t) = (3 cos 31) i+ (3 sin 3t) j such C that Osts 2n. The area of R is | |. (Type an exact answer, using it as needed.)
