16, -9 and radius 2. Using my equation from before.

anonymous · Answer

it will work here to ?? it is worded differently and u dont have the radius is not give ??

anonymous · Answer

Well, in that case, it gave the center and radius, asked for equation of circle. Here, it gave the equation of circle and asked for center and radius. You can go back-and-forth using the same fundamental principle of the equation of the cirlce I showed.
