This educational illustration displays the geometric net of a 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 circumference of the base circle. Designed for clarity, it supports spatial reasoning and volume/surface-area calculations in middle and high school math.

Used in K-12 math curricula, textbooks, and online learning platforms to teach 3D shape nets, surface area derivation, and geometric visualization; targets students and educators seeking intuitive understanding of cone structure.
