Figure 4 shows a cross-section of a composite structure. Determine: (a) the coordinate of centroid C for the cross-section. (b) the moments of inertia for the cross-sectional area about the x-axis, Ix. (c) the volume of the structure by revolving the shaded area about the y-axis using the theorem of Pappus-Guldinus.
