Yes, those are the coordinates of your CG. But why are you working so hard? The simple mean gives you more accurate answers:
The extension to two materials is straightforward - see 2D example below. The further extension to 3D is also straightforward (as long as you remember to replace R^2 by R^3, and take cube roots instead of square roots, etc.);
