Coordinates of center and radius of circle is
.
<u>Step-by-step explanation:</u>
Here we have , The equation of a circle is given below.
(2 – 13.4)2 + (y + 2.6)2 = 100 or , 
We know that , Equation of circle is given by :
⇒
...........(1)
where (h,k) are the coordinates of center of circle and r is the radius of circle . Let's simplify given equation of circle in question ;
⇒ 
⇒ 
⇒ 
Comparing this equation to (1) we get :

Therefore , Coordinates of center and radius of circle is
.
