Annulus Shape Diagram - Geometric Ring Illustration #319653 (License: Personal Use)

This image displays a classic annulus - a ring-shaped region bounded by two concentric circles of different radii. The clean black outlines on a white background emphasize symmetry and spatial relationship, making it ideal for educational diagrams or technical schematics. It visually conveys concepts like area calculation, rotational symmetry, and cross-sectional views.

Used in mathematics textbooks, online geometry tutorials, engineering drawings (e.g., washer or pipe cross-sections), and UI design to represent circular zones or loading indicators. Matches user intent for learning geometric shapes or sourcing vector illustrations.
