### Problem b)

Consider the diagram provided, which features a square with dimensions of 9 meters on each side. Within this square, there's a notably shaped region formed by the curves of four quarter circles, each with a radius of 4.5 meters (half of the square's side length).

#### Description of the Diagram:
- **Square Dimensions**: Each side of the square is 9 meters long.
- **Quarter Circles**: The four curves forming the inner region are part of quarter circles centered at each corner of the square.
- **Intersecting Region**: The curves intersect, creating a star-like shaded area in the middle of the square.

#### Diagram Analysis:
Each curve within the square reaches from one corner of the square to the midpoint of an adjacent side, effectively forming quarter circles with radii of 4.5 meters. As these quarter circles intersect inward, they delineate a distinctive star-like shaded region in the center of the square.

This diagram is useful for visualizing the spatial relationships and areas formed by the intersection of circular arcs within a confined space, illustrating how circular geometry principles apply to more complex shapes.

### Image Description for Educational Website

The image presented is a geometrical diagram featuring a circle with a unique pattern within it. The circle has a diameter of 5 inches.

#### Diagram Explanation:
- **Circle**: The outer boundary outlines a full circle with a specified diameter.
- **Inner Pattern**: Inside the circle, there appears to be a pair of complementary regions that resemble a yin-yang symbol. These regions divide the circle into two equal areas with a curvilinear boundary separating them.
- **Measurement Notation**: On the right side of the circle, there is a vertical line with the label "5 in.", indicating the diameter of the circle.
