Answer:

Center point:
(-4,6)

Radius:
r=5

Explanation:

The equation of a circle is
(x-h)^2+(y-k)^2=r^2 where
(h,k) is the center point of the circle and
r is the radius of the circle.

Given our equation
(x+4)^2+(y-6)^2=25, we can see that
(h,k) is
(-4,6) and since
r^2=25, our radius is
r=\sqrt{r^(2) } =√(25) = 5

Therefore, the center point is
(-4,6) and the radius is
r=5
