Question

3) Identify the center and radius

Answer 1

Case: Circle equations

Metho:

`(x-a)^2+(y-b)^2=r^2`

Given:

`\begin{gathered} (x+11)^2+(y-6)^2=9 \\ (x+11)^2+(y-6)^2=3^2 \end{gathered}`
`\begin{gathered} Center(a,b)=(-11,6) \\ radius,r=3 \end{gathered}`

Final answer:

Center (-11, 6)

radius, r= 3
