What is the relationship between the volume of a cone and a cylinder with the same base radius and height?
The volume of the cone is the same as the cylinder.
The volume of the cone is twice the volume of the cylinder.
The volume of the cone is one-third the volume of the cylinder.
The volume of the cone is half the volume of the cylinder.
설명
The volume of a cone is 1/3πr²h, while the volume of a cylinder is πr²h. So the cone's volume is one-third that of the cylinder.
