A sphere is the set of points which are all within the same distance from a given point in space.
Calculating the volume of a sphere is possible using an appropriate cylinder and cone.
This animation presents the formulas to calculate the perimeter and area of shapes as well as the surface area and volume of solids.
This 3D scene explains the correlation between the ratio of similarity and the ratio of volume of geometric solids.
The surface of a sphere consists of the set of points which are all at the same distance from a given point in space.
Rotating a geometric shape around a line within its geometric plane as an axis results in a solid of revolution.
An exercise about the volume and surface area of solids generated from a ´base cube´.
To calculate the volume of a tetrahedron we start by calculating the volume of a prism.
