Answer:

Explanation:
The center of the circle is (0, -2). The dark-filled circle is the center and lies 2 units below the origin on the y-axis.
On the other hand, the radius of the circle is 3 units. If we count from the dark-filled circle, we have 3 complete squares to the left, to the right.
Now the standard equation of a circle with center (a, b) and radius r units is given by the formula;

Substituting the values obtained;

and is our standard equation of the given circle
