cone

A cone is a three-dimensional geometric shape with a circular base that tapers smoothly upward to a single point called the apex or vertex. Think of it as a rounded, pointed object—like an ice cream cone—where the flat circle is at the bottom, and the sides slope inward toward the tip. Cones are common in both nature and design, often used in architecture, engineering, and everyday objects. They have a curved surface and a circular opening at the base, making them distinct from other shapes like cylinders or spheres.
