The hidden line is drawn, however, the edges of the center line can still be seen ( the center line ends up appearing as extra long dashes on either side of the end of the hidden line)
The point from which the circle is drawn IS the center.
No.
Yes.
radius
The center of a circle is the same for all circles but the length of the radius can change
On engineering drawings, the priority hierachy is object line, hidden line, center line. A centerline can be drawn extending beyond the physical edges of the part, a hidden line cannot. The hidden line (equally spaced short dashes) is drawn on the part instead of the centerline (alternating long dash, short dash, long dash)when the two lines are stacked in a view. If an object line, hidden line and center line are stacked in a view, the object line takes priority and is shown on the drawing. The centerline in both instances can be shown extending beyond the part edges for clarity.

The politician gave another long, drawn out speech. That water was drawn from this well. That picture was drawn with charcoal. There goes a horse drawn carriage!
Hansom is a horse drawn cab.
The line drawn from the center of a regular polygon and perpendicular to a side.

It's KC(4)H(5)O(6). It is often incorrectly drawn with the center 2 C atoms having only 3 bonds. Of course there is a hidden H on each, not drawn. Perhaps because optically the invisible H's are, in 3-D, below the page. Who knows the reason for this error...
The point in a painting where the eye is drawn to is known as the Focal Point.
