Here's a step-by-step solution: Part (i): Show that the centre of mass of the quarter circular portion ACD is at a distance (4a)/() from the bounding radii AC and CD. Step 1: Identify the properties of the quarter circle. The quarter circle ACD has its center at C and radius R = AC = CD = 3a. Step 2: Apply the formula for the center of mass of a quarter circle. For a quarter circle of radius R, the coordinates of its center of mass from the center of the circle, along the bounding radii, are ((4R)/(3), (4R)/(3)). Step 3: Substitute the given radius
