    Sector of circle, radius r, angle at centre 2α : ((2r)sinα)/3α from centre

    This is for finding the centre of mass of a segment, so I'm unsure whether it's the same for finding the centre area, I assume so

    I am trying to locate the centroid of the area (or centre of mass) of a segment of an arch ring. I have calculated the centroid shown by approximately breaking the curve into equivalent triangles and squares and applying the parallel axis theorem, however am sure the results have significant error. I Know the radius and can calculate the formula of the curve if this helps.

    Any help would be much appreciated...

    p.s. only interested in finding the horizontal distance (i.e. x-axis)

    Sorry, this question is officially out of my depth, but it would be better (and you'd more likely get a suitable reply) if you post a thread in the Maths Forum here
