Answer:
c. (0, 0)
Step-by-step explanation:
You want the coordinates of the center of the circle x² +y² = r².
Circle equation
The standard form equation for a circle is ...
(x -h)² +(y -k)² = r² . . . . . . center at (h, k)
When we have x-h =x, then h=0. Similarly, when y-k=y, then k=0.
The values of (h, k) for the given circle are (0, 0), choice C.
