- Homework Statement
- centroid of a body consisting of two planes

- Relevant Equations
- centroid of semi circle = (4R / 3 pi, 4R / 3 pi)

centroid of rectangle = (b/2, h/2)

centroid of triangle = (b/3, h/3)

I found the centroid of four sections, 2 semicircles, 1 rectangle (xz plane) and the remaining right triangle.

I tabulated the individual centroids (x,y,z) of the 4 sections, multiplied each one with the Area of respective section. In the end I calculated the required (x,y,z) by dividing (sum of xA) by (total area of body). I'm getting wrong answer, Please help
