Finding the radius of a circle inscribed in a hexagon

In this video I show how to find the radius of a circle inscribed in a hexagon. The concepts covered in this question include inscribed shapes, regular hexagons, 30-60-90 triangles, trig ratios, tangents to a circle, interior angle sum of polygons, regular polygons, solving equations. Wri

How Many Faces, Edges And Vertices Does A Hexagonal Prism Have?

How Many Faces, Edges And Vertices Does A Hexagonal Prism Have? Here we’ll look at how to work out the faces, edges and vertices of a hexagonal prism. We’ll start by counting the faces, these are the flat surfaces that make the shape. A hexagonal prism has 8 faces altogether - 2 hexagon

AlgTop21: The two-holed torus and 3-crosscaps surface

We describe how the two-holed torus and the 3-crosscaps surface can be given hyperbolic geometric structure. For the two-holed torus we cut it into 4 hexagons and then describe a tesselation of the hyperbolic plane (using the Beltrami Poincare model described in the previous lecture) compo

The Meaning of Pi

More important than knowing a bunch of digits in the decimal approximation of Pi is to understand what Pi means. Pi is the ratio of the Circumference to the Diameter of any circle. Multiply the diameter by Pi to get the circumference or divide the circumference by pi to get the diameter.
