Frequently Asked Questions

No! The height must be the straight perpendicular line from the center of the base to the top point. Slant length is the distance along the outside surface.

Yes. The volume formula works for oblique cones as long as the height is the perpendicular distance from the base plane to the apex.

A frustum is a cone with the top chopped off. This calculator only works for complete, pointed cones.
