Can I get some help with my MATLAB code? The awnser seems correct, and I know the format is generally what's wanted, but it's just not coming back right

rbar11 = [r*cos(theta),r*sin(theta),9 - r^2];

F11 = [y,x,z];

q11= int( int(simplify(dot(subs(F11,[x,y,z],rbar11), cross(diff(rbar11,theta), diff(rbar11,r)))), r, 0, 3), theta, 0, 2*pi)
