ANSWER
The diameter is 8 units.
EXPLANATION
A portion of the y-axis is serving as the diameter of the circle.
The portion of the y-axis that intersects the circle at two points.
We can use these intercepts to find the diameter.
There is a y-intercept at y=2 and y=-6.
The distance between the two intercepts is the diameter of the circle.
Therefore the radius is 8 units.
