Answer:
The coordinates of the center are (4, -4).
Explanation:
If a circle lies on the fourth quadrant and touches both the x-axis and y-axis, it means its center is equidistant from both axes. Given that the radius is 4 units, the center of the circle will be 4 units to the right and 4 units down from the origin (0,0).
Therefore, the coordinates of the center are (4, -4).
