Previous Surface Area of a Cone Next Volume of a Cylinder
  • The volume of a cone is proportional to the radius of the circular base squared and the height of the cone
  • The formula for the volume of a cone is V = (1/3)��r^2h
  • The volume of a cone is one third the volume of a cylinder with the same base and height
  • The volume can be calculated using either a known base area or the radius of the base
  • The volume of a cone can be written as V = (1/3)��r^2h
  • To calculate the volume of a cone, you need to know the height and radius of the base
  • The volume of a cone can be calculated by taking the area of the base (��r^2), multiplying by the height (h), and multiplying by a third
  • In the example given, the cone has a radius of 4 cm and a height of 12 cm, resulting in a volume of 201 cm^3 (to 3 significant figures)
