If a cone has the same radius and height as a cylinder, the volume of the cone is _

the volume of the cylinder. If a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, then the volume of the sphere is
_ the volume of the cylinder.

If a cone has the same radius and height as a cylinder, the volume of the cone is 1/3 the volume of the cylinder.

If a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, then the volume of the sphere is (4/3) times the volume of the cylinder.
