The equation of a circle is


(x-h)^(2)+(y-k)^(2) = r^(2)

So this equation you provided has:
Center: (2,-8)
Radius: 4

Answer:

The center of the circle is (2, -8)

Explanation:

Given : the equation of circle as
(x-2)^2+(y+8)^2=16

We have to find the center of the circle whose equation is
(x-2)^2+(y+8)^2=16

The general equation of a circle is given as
(x-h)^2+(y-k)^2=r^2

Where , (h,k) represents the center of the circle and r represents the radius of the circle.

Comparing the given equation of circle
(x-2)^2+(y+8)^2=16 with the general we get,

h = 2 , k = -8 and r = 4

Thus
(x-2)^2+(y+8)^2=16 can be written as
(x-2)^2+(y-(-8))^2=4^2

Thus, the center of the circle is (2, -8)
