The Pyramid and the Cone
Comparing the pyramid and the cone
Comparing the pyramid and the cone
| Feature | Pyramid | Cone |
|---|---|---|
| Base | A polygon | A circle |
| Lateral faces | Triangles | One curved surface |
| Height | The perpendicular distance from the apex to the base | The perpendicular distance from the apex to the centre of the base |
| Slant height | Height of a lateral face | The generator, with l² = r² + h² |
- A pyramid and a cone both consist of a base and an apex.
- We will see in the next lesson that the volume of each of them depends on the area of the base and the height by the same rule.
