What type of base does a cone have?

  1. Square

  2. Rectangle

  3. Circular

  4. Triangular

The correct answer is: Circular

The base of a cone is circular, giving it a unique shape that distinguishes it from other three-dimensional figures. This circular base allows the cone to transition smoothly to its apex (the tip), resulting in the characteristic pointed structure that we associate with cones. In geometry, the circle serves as the foundational shape from which the sides of the cone rise to the apex, making it essential to define the cone accurately. The other shapes mentioned, such as square, rectangle, and triangular, represent different types of bases found in other geometrical figures, but none accurately describe the base of a cone.
