Make the circle as a shape.
Convert circle to a path.
Select two of the four control nodes, insert a node.
Inserted node will appear at midpoint on path between selected nodes.
Do not move any nodes yet, you'll damage path's circularity.
Repeat steps 3,4 recursively until you have a node close enough to your
desired cut point at each side of the segment to be removed.
Hmm, why can't you just drag the rightmost controls of the circle as shape, without converting to path? That's exactly what these controls are for. If you don't need the radii, drag the controls from inside the circle. Use Fill&Stroke dialog to remove fill if you don't need it. It's very easy to create an arc of any angle, with or without radii, using these controls. Dragging the controls with Ctrl snaps the angle.
And yet another simple way to do this (not necessary for ellipses because they have the controls, but useful for other paths): just draw your shape, then draw a separate cut-out path which intersects the first shape in the points you want to cut, select both and do Path > Cut Path, then remove the portion of the shape that you have cut out.
