Best ResponseYou've already chosen the best response.0\[\large (xh)^{2}~+~(yk)^{2}=r^{2}\] \[\large (h,k)~=~Center~coordinates~of~circle\] \[\large r~=~radius\]

Best ResponseYou've already chosen the best response.0So if we break down each part it will look like this \[\large (xh)^{2}~=~(x12)^{2}\] From that, what would h be? \[\large (yk)^{2}~=~(y32)^{2}\] From that, what would k be? \[\large r^{2}~=~49\] From that, what would r be?
