Sphere Diagram - Visual Representation of a 3D Geometric Shape #3676679 (License: Personal Use)

This black-and-white schematic depicts a perfect sphere with a horizontal dashed line representing the equator or a great circle, separating the upper and lower hemispheres. The solid outer circle outlines the full 3D shape in 2D projection, while the curved solid line below indicates the visible boundary of the lower hemisphere. It’s a standard representation used in mathematics and physics to convey spherical symmetry and spatial orientation.

Commonly used in educational content (e.g., K-12 math, college geometry, astronomy), technical documentation, or interactive learning platforms where users seek visual clarification of 3D shapes, volume calculations, or spherical coordinates. Matches intent for “sphere diagram,” “geometric shape illustration,” or “hemisphere definition.”
