not sure if this is what you mean, but this is a manual, old-school, geometry-based, visual method of finding the centre:

if you know the diameter of the circle (the w width in inkscape), then draw a horizontal line line that long. drop it across the circle, so the ends are on the edge. do the same with a vertical line.

where they cross is the centre of the circle.

as i said, this is manual, but it should give you a good idea as to where the centre is.

if you need the exact co-ordinates of the centre, then you should be able to do it from the x,y, w, h details of the circle. x + half w, y+ half h.

Hi everybody Guillaume from France here. I'm not exactly new to inkscape (I started with Sodipodi a few years ago actually) , but I can't find how to trace the center of a circle. Can someone help? Thanks Guillaume
