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: 4
Center: (-16, 9); Radius: 2
Center: (16, -9); Radius: 2
Center: (-16, 9); Radius: 4

Answer 1

\[Is \it : (x-16)^2+(y+9)^2=4 \]

Answer 2

The standard form of circle is \[(x-h)^2+(y-k)^2=r^2 \] where h and k are centre of circle and r is radius. now u can compare and will get ur answer
