Susiję elementai

### Susiję elementai #### Sphere

A sphere is the set of points which are all within the same distance from a given point in space. #### Volume of spheres (Cavalieri´s principle)

Calculating the volume of a sphere is possible using an appropriate cylinder and cone. #### Perimeter, area, surface area and volume

This animation presents the formulas to calculate the perimeter and area of shapes as well as the surface area and volume of solids. #### Ratio of volumes of similar solids

This 3D scene explains the correlation between the ratio of similarity and the ratio of volume of geometric solids. #### Surface area of spheres (demonstration)

The surface of a sphere consists of the set of points which are all at the same distance from a given point in space. #### Solids of revolution

Rotating a geometric shape around a line within its geometric plane as an axis results in a solid of revolution. #### Volume and surface area (exercise)

An exercise about the volume and surface area of solids generated from a ´base cube´. #### Volume of a tetrahedron

To calculate the volume of a tetrahedron we start by calculating the volume of a prism.
