Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:

They want the cones to hold the same volume of 9 cubic inches.
If height is 3:



r = 1.69 inches

If radius is 2:


h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.
