it's truncated cone joined, at it's small end, to a cylinder

A three-dimensional figure that closely resembles a funnel is a truncated cone joined, at its small end, to a cylinder. To understand this, visualizing it can be helpful.

To get a better understanding, you can follow these steps to create a basic funnel shape:

1. Start with a right circular cone. This cone has a circular base and tapers to a single point at the top.

2. Next, imagine cutting off the top portion of the cone horizontally, parallel to the base. This creates a flat circular top surface, resulting in a truncated cone.

3. To complete the funnel shape, join the small circular opening left from the truncated cone to a cylinder. Imagine attaching the small opening of the truncated cone to a tube-like structure with a circular base, forming the cylinder.

By combining these two shapes, you'll get a figure that resembles a funnel. The wider end of the truncated cone represents the opening, while the cylinder represents the tube-like part of the funnel.
