Question
--- **Educational Content on Calculating the Moment of Inertia** ### Problem Determine the moment of inertia of the given area about the y-axis. Given that \( R = 1.5 \) inches. ### Figure Explanation In the given diagram, we are presented with a composite shape consisting of a rectangle with a triangular cutout and a circular cutout. The dimensions and positions are as follows: - The larger rectangle has a width of 6 inches (3 inches on either side of the triangular cutout) and a height of 10 inches (4 inches below the circular cutout and 6 inches above). - The triangular cutout has a base of 6 inches and a height of 6 inches, forming a right triangle. - The circular cutout has a radius \( R \) of 1.5 inches and is positioned such that its center is 4 inches from the bottom edge of the rectangle and 3 inches from the left edge. ### Diagram Details - The x and y axes are labeled, with the x-axis extending horizontally and the y-axis vertically. - Distances along the x and y axes are marked with appropriate dimensions. ### Dimensions Provided - The overall width from left to right of the composite shape is 6 inches. - The overall height from top to bottom of the composite shape is 10 inches. - The circular cutout centered at (3 inches, 4 inches) has a radius of 1.5 inches. ### Task Using the provided dimensions and the properties of the composite shape, calculate the moment of inertia of the entire area about the y-axis. ---
