Cone Net Diagram - Geometry Education Resource #1478220 (License: Personal Use)

This educational diagram displays the net of a right circular cone, composed of a circular base and a sector-shaped lateral surface that wraps around to form the cone’s side. The sector’s radius equals the cone’s slant height, and its arc length matches the base circumference. The supporting base illustration shows how the net folds into a 3D shape.

Used in K-12 math curricula and online geometry tutorials to teach surface area, volume, and spatial reasoning; supports lesson plans on 3D figure nets and hands-on modeling activities.
