- Center =

- Radius =

<u>Step-by-step explanation:</u>
Here we have following equation : 
We need to find the center & radius of this circle . Let's find out:
We know that , Equation of a circle is given by :
⇒
........(1)
Here , (h,k) are the co-ordinates of center & r is the radius of circle.Collectively called as a circle with radius r and center at (h,k) . Let's frame given equation in question :
⇒ 
⇒ 
On comparing this equation with equation (1) we get :
- Center =

- Radius =
