Answer:
The center is at (5, -3) and the radius is 5
Step-by-step explanation:
The equation for a circle is given by
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center of the circle and r is the radius of the circle.
(x - 5)2 + (y + 3)2 = 25
Rewriting the equation
(x - 5)2 + (y - -3)2 = 5^2
The center is at (5, -3) and the radius is 5
