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
What is a cone?A cone is a solid created in the following way: Take a circle and a point right over the center of that circle. Connect this point with the border of the circle, and you get a cone.
What are formulas for cones?These are the cone formulas: The base area equals Pi*r^2 (cause it is a circle). For the volume, the formula V=1/3*G*h holds, where G is the base area and h is the height.
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.
