    the general equation of a cirle is \[(x-h)^{2} + (y-k)^{2} = r ^{2}\] compare this to your equation and find "r"

    \[r=\sqrt{g^2+f^2-c}\] \[r=\sqrt{16-(-24)}=\sqrt{16+24}=\sqrt{40}\]

    in this case compare your equation to \[x ^{2} + y ^{2} + 2gx + 2fy + c = 0\] where \[r = \sqrt{g ^{2} + f ^{2} - c}\]
