Answer

Center: (16, -9); Radius: 2

Center: (-16, 9); Radius: 2

Center: (16, -9); Radius: 4

Center: (-16, 9); Radius: 4

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

thank you again XD
