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

Center: (16, 9); Radius: 2
\[(x−h)^2+(y−k)^2=r^2\]
h and k are the coordinates of the center, and r is the radius.

Answer 2

Thank you sosososoo much!
