Question

Find the centroid’s x and y coordinates to 3 significant digits relative to the bottom right corner. Each semicircle has a radius of 4 cm. The dimensions in cm are not to scale.

 

The image illustrates a geometrical shape featuring both circular and triangular elements positioned on a coordinate plane.

### Description:

1. **Semicircles**: 
   - Four semicircular arcs are integrated at the top of the shape.
   - The radius of each semicircle is denoted as R4, meaning each semicircle has a radius of 4 units.

2. **Right Triangle**: 
   - A right-angled triangle is cut out from the shape. 
   - The triangle has a horizontal base measuring 6 units and a vertical height of 5 units.

3. **Measurement Labels**:
   - A horizontal line labeled as 10 units extends across the shape from the vertical side of the triangle to the far right.
   - Vertical line segments indicate the total height of the shape as 24 units.
   - Additional measurements include a line segment labeled "y" positioned vertically and a line segment labeled "x" positioned horizontally close to the origin.

### Coordinate Axes:
- The shape is positioned within a coordinate system, denoted with the usual x and y axes.
- The x-axis extends horizontally, while the y-axis extends vertically, with a measurement of 5 units indicated near the base of the triangle.

This detailed explanation serves as an educational reference to understanding the composite shapes and spatial measurements in the diagram.
