Geometry

The cone is a solid object with a circular base and a side surface that converges to a single point, the apex.

The volume of a cone is given by the formula:

V = \frac{1}{3} \pi r^2 h

where r the radius of the circular base and h the height of the cone. This formula is derived from the following general expression, that also covers all pyramids, with any polygonal base:

V = \frac{1}{3} A_b h

where A_b the base area.

The lateral surface area of the cone can be found using the following formula:

A_f = \pi r L

where L the lateral height of the cone, which is easily found as:

L = \sqrt{h^2+r^2}

Since the area of the circular base is equal to \pi r^2 , the total surface area of the cone is:

A = \pi r^2 + \pi r L
