A cone is a three-dimensional solid with one circular base and a curved surface that narrows to a single point, called a vertex. The shape can be identified in different orientations and distinguished from a cylinder, which has two circular bases, and a sphere, which has no flat faces or vertices; measurements, formulas, and classifications of cones are not included.

Detailed Explanation: Identify cones
A cone is a solid shape with:
- One flat, circular base
- A curved side
- One point, called a vertex
The point may be on top, on the bottom, or on the side if the cone is turned.
Example: Which object is shaped like a cone?
- A. A soup can
- B. An ice cream cone
- C. A ball
Step 1: Look for a point.
The ice cream cone has one point. The can and ball do not.
Step 2: Look for one circular base.
The ice cream cone has one round, flat opening at the top. Its sides curve down to the point.
Step 3: Check the other shapes.
The soup can has two circular bases, so it is not a cone. The ball has no flat base or point, so it is not a cone.
Answer: B. An ice cream cone is a cone.
