A truncated cone, also known as a conical frustum, is a three-dimensional shape that is formed by cutting the top off of a cone with a plane parallel to its base. The resulting shape is a truncated cone with two parallel bases of different sizes connected by a curved lateral surface.

Truncated cones can be found in a variety of real-life objects, such as ice cream cones, traffic cones, megaphones, and lampshades. The shape is also commonly used in architecture, with examples including the spires of Gothic cathedrals and the roofs of some traditional Japanese buildings.
