Draw_Circle(X, Y, Radius, Color, Filled)
Draw_Circle is a call that draws a circle whose center is (X,Y) and whose radius is given.
Color specifies a color.
Filled can be either True (also Filled or Yes) or False (also Unfilled or No). If True, the circle will be filled in with the given color. If False, the circle will be drawn with no internal fill.
Note: A graphics window must be open when Draw_Circle is called or a run-time error will occur.
