Frank,
A section of a geometric solid like a cone formed by passing horizontal
parallel planes through the solid generates a frustum. Practically speaking
when applied to tree trunks, frustums are just sections of the trunk. There are
formulas to compute the volumes of frustums of different solids. If D1 and D2
are diameters of the top and bottom sections and H is the height of the
frustum, the volume is given by:
V = H*PI/12*[D1^2 + D2^2 + D1*D2]
