QuestionCircle A in the xyx y-plane has the equation (x+5)2+(y5)2=4(x+5)^{2}+(y-5)^{2}=4. Circle B has the same center as circle A. The radius of circle B is two times the radius of circle AA. The equation defining circle B in the xyx y plane is (x+5)2+(y5)2=k(x+5)^{2}+(y-5)^{2}=k, where kk is a constant. What is the value of kk ?
