Unit 5 - Lesson 16 - Grade 8: Illustrative Mathematics

The volume of this cone with height 3 units and radius r is V = 64π cubic units. This statement is true: What does the radius of this cone have to be? Explain how you know.

Which container is the better value? Use 3.14 as an approximation for π.

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9π cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
