Answer:

The center of the circle is D (12, -5)

Explanation:

To solve this problem, we will first write the standard equation of a circle then compare it with the equation given.

The standard equation of a circle is given by;

(x - a)² + (y-b)² = r² ---------------------------------------------------------------------(1)

where (a,b) is the center of the circle and r is the radius of the circle

From the question, the equation of the circle given is;

(x – 12)² + (y + 5)² = 100 --------------------------------------------------------------(2)

Comparing equation 1 and equation 2

The center of the circle is (12, -5)

D is the correct option
