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