This video demonstrates how to find the volume of circular shapes such as spheres and cones, which both require the use of the circle formula. It also explains how the revolution of one shape can create another three dimensional shape with a circular quality.

The narrator explains that mathematics is much more than simply numbers and equations. He shows how different shapes, such as spheres and cones, can be found in nature and are used in technology both at home and in several industries.

This video demonstrates an example of how to find the volume of a cylinder using the circle formula.

Beakman explains that the seasons are created by the Earth's axis being tilted. He brings Capernicus in to explain more and then uses a model to show how depending on Earth's orbit and axis the amount of sun on a given portion will affect seasons.
