Frustum of a cone

Drawing of a frustrum cone
You can calculate the volume with this formula:

V=frac{1}{3}*pi*h*({r_1}^2+{r_2}^2+r_1*r_2)

V = volume

r1 = radius of the small circular end plane

r2 = radius of the big circular end plane

h = height of the frustum

Calculate the volume and the area of a frustum of a cone
