When making a shape, for example a simple circle with a black stroke/outline

and then trying to fill in a solid color with the paint bucket

I find that there are some areas that remain white, mainly around the stroke color. how do I get the fill color and the stroke color to meet completely without white spaces?
I'm sure this is posted somewhere else, for which I apologize, but I was unable to find it and I'm a newbie to inkscape and this forum.
Thanks!
