# Cone calculation

For a cone, these formulae hold:

Base area = pi * Radius^2

Volume = 1/3 * base area * height

Lateral height = square root of (height^2+radius^2)

lateral area: pi*radius*side height

Surface = base area + lateral area

For the distance between upper point and circle border, the formula s^2=h^2+r^2 holds (gotten from Pythagoras' theorem).

Last but not least, the furmula M=Pi*r*s gives the lateral area of the cone.

For further information, just move your mouse over one of the following words, and the corresponding piece of the cone will be marked.
