Three different cones are used for the storage of food. They are related as follows:
• Cone A has radius of r and height of h.
• Cone B has 3 times the height of Cone A but has the same radius.
• Cone C has 4 times the radius of Cone A but has the same height.
A. Determine the ratio, A:B:C, of the volumes of the cones?
B. What Knowledge do you apply for this question and what did you learn from this lesson?
