Conical Frustum Roll
The plastic cup above can be considered a conical frustum. It has 9 cm of height. The greater base has a diameter of 6 cm, and the smaller one has a diameter of 4 cm. If you roll it (like rolling a barrel) on a frictionless surface, it will draw something we can consider that is a perfect circumference. What is the area, in square centimeters, of the cirfumference that was drawn?
Note: use \(\pi = 3 \).
