A right cone is a three-dimensional geometric shape that tapers smoothly from a flat circular base to a single point called the apex. The axis of the cone is a straight line that runs from the center of the base to the apex, and it is perpendicular to the base. In a right cone, the radius of the base determines the size of the cone, while the height is the distance from the base to the apex. This shape is commonly seen in everyday objects, such as ice cream cones and traffic cones.
