A cone is a pyramid, usually with a circular base, which tapers to a point at the top, called the vertex or apex.
If the vertex is directly above the centre of the base, the cone is called a right cone.
There are three key measurements for a cone.
The radius, r
Volume of a Cone
The volume of a cone uses the formula for the volume of a pyramid
Surface Area of a Cone
The surface area of a cone is the sum of the area of the base and the area of the curved surface of the cone.
