3 · Cone volume formula. A cone is a solid that has a circular base and a single vertex. To calculate its volume, you need to multiply the base area (area of a circle: π × r²) by height and by 1/3: volume = (1/3) × π × r² × h. A cone with a polygonal base is called a pyramid – see pyramid volume calculator.

· The properties of 3D shapes are faces, edges and vertices. Faces are the flat or curved surfaces that make up the outside of a 3D shape. Edges are the lines where two faces on a 3D shape meet. Vertices are the corners of a 3D shape formed where two or more edges meet. For example, a cube has 6 faces, 12 edges and 8 vertices.

The area of the square is 2x × 2x = 4x2. The ratio of the circle to the square is π: 4. The same is true for every slice we take: the area of the circle is π 4 of the area of the square. So, if each slice is π 4 the size, the volume of the cone will be π 4 the volume of the pyramid. The pyramid's volume is (2r)2h 3 = 4r2h 3.
