Use the image to answer the question.
Aimee packs ice cream into an ice cream cone. She then puts a perfect hemisphere of ice cream on
top of the cone that has a volume of 4 in.³ The diameter of the ice cream cone is equal to its
height. What is the total volume of ice cream in and on top of the cone? Use the relationship
between the formulas for the volumes of cones and spheres to help solve this problem. Show your
work and explain your reasoning.
