**Problem 9-64:**

**Task:** Locate the centroid (\( \bar{x}, \bar{y} \)) of the shaded area.

**Diagram Explanation:**

The diagram shows a composite shape that is composed of a right triangle, a rectangle, and a semicircle. Here are the key measurements and features:

- **Right Triangle (Left Section):**
  - Base: 3 inches
  - Height: 1 inch

- **Rectangle (Middle Section):**
  - Width: 3 inches
  - Height: 1 inch

- **Semicircle (Right Section):**
  - Radius: 3 inches
  - Center aligns with the right edge of the rectangle

The shape is symmetric about the \( y \)-axis, with axes shown as coordinates \( x \) and \( y \), and the semicircle oriented such that its flat side aligns with the top edge of the rectangle and triangle. The task is to determine the location of the centroid for this composite shape.
