Fill and unfold them to make the formulas come alive. Compare a cone with a cylinder to confirm its volume is exactly 1/3, unfold its side into a sector, and compare a sphere with a snug cylinder to discover the 2/3 relationship.

About this app
An interactive middle-school geometry app for exploring the surface area and volume of cones and spheres. Adjust cone radius and height to verify that a cone has one-third the volume of a matching cylinder, unfold the cone’s side into a sector, and compare a sphere with its snug cylinder to see the two-thirds volume relationship.
Use cases
- Middle-school students learning solid geometry
- Teachers demonstrating cone and sphere formulas
- Learners investigating how radius and height affect measurements
- Classroom or self-study activities on volume and surface area
Features
- Interactive cone and cylinder volume comparison with adjustable radius and height
- Step-by-step unfolding of a cone’s side into a sector
- Displays the slant length and explains its relationship to the sector radius
- Sphere volume and surface area calculations for adjustable radii
- Optional comparison with a snug cylinder whose height equals the sphere’s diameter
- Mission-style activities with reset and next controls
