For the following vector field, compute (a) the circulation on and (b) the outward flux across the boundary of the given region. assume the boundary curve has a counterclockwise orientation. f = (3x + y, x^2 - 3y), where r = {(x, y): y^2 lessthanorequalto x lessthanorequalto 50 - y^2}

the circulation on the boundary is.
the outward flux across the boundary is .
