Please help me with this question
1 answer:
The equation of a circle is:
where center is (h,k) and radius is r. Therefore, in this question, you need to check if the (h,k) values are the same. Let's view each option and judge accordingly:
A. (0,-4) and (-4,0) : Nope
B (-3,3) and (3,-3) : Nope
C. (7,2) and (-7,-2) : Nope
D. (2,5) and (2,5): Yes, the centers are equal.
Therefore, your answer is option D.
