A circle C has center at the origin and radius 6. Another circle Khas a diameter with one end at the origin and the other end at thepoint (0,14). The circles C and K intersect in twopoints. Let P be the point of intersection of C and K which lies inthe first quadrant. Let (r, \theta ) be the polar coordinates of P, chosen so that r is positive and 0 \leq \theta \leq 2. Find r and \theta. Note: I was able to find that r=6 which is the correct answer, thenusing the x and y values of the point of intersection I did thearctan(y/x) to find \theta, but that's not giving me the rightanswer, is there another method to find \theta that I'm forgetting?
