frustum

Physics

A solid figure produced when two parallel planes cut a larger solid or when one plane parallel to the base cuts it.

Mathematics

A frustum of a right‐circular cone is the part between two parallel planes perpendicular to the axis. Suppose that the planes are a distance h apart and that the circles that form the top and bottom of the frustum have radii a and b. Then the volume of the frustum equals $\frac{1}{3} π h (a^{2} + a b + b^{2})$ .

Let l be the slant height of the frustum; that is, the length of the part of a generator between the top and bottom of the frustum. Then the area of the curved surface of the frustum equals π‎ (a + b)l.
