Question

Circle S has an equation of (x – 16)2 + (y – 9)2 = 4. What is the center and radius of circle S?

Center: (16, 9); Radius: 2

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

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

Center: (16, 9); Radius: 4

Answer 1

the general form of the equation of circle is
(x-x1)^2+(y-y1)^2=r^2
where (x1,y1) is center and r is radius
does this help?

Answer 2

yes thanks! :)
