What is volume of cone
a cone is a circular pyramid. (because the bottom of a cone is a circle and then it goes up to a point at the top.)
The volume of any pyramid is 1/3 * the area of the base * the perpendicular height
The base is a circle so it's Area is pi * r^2
so,
The volume of a cone must be 1/3 * pi * r^2 * h
