**Problem Statement:**

3. For the plate shown to the right, determine the location of the centroid.

**Answer:**

\(\bar{x} = 0\), \(\bar{y} = 0.018 \text{ in.}\)

---

**Diagram Explanation:**

The diagram illustrates a composite plate consisting of a semicircle and a rectangle, with a smaller square cutout.

- The semicircle has a radius of 6 inches and is positioned on the left side. 
- The rectangle is positioned to the right of the semicircle, measuring 5 inches in width and 6 inches in height.
- A square with sides of 2 inches is cut out from the top right corner of the rectangle.
- Dimensions are marked to show distances across the structure:
  - The distance from the leftmost edge to the edge of the semicircle is 3 inches.
  - Horizontal and vertical axes are marked as x and y, respectively.
  
**Key Measurements:**

- Semicircle radius \(r = 6\) inches.
- Rectangular section: 5 inches wide, full height of 6 inches.
- Cutout square: 2 inches by 2 inches.

The centroid's coordinates are provided with respect to the origin set at the center of the semicircle's flat side.
