Pablo’s Icy Treat Stand sells home-made frozen juice treats as well as snow-cones. Originally, Pablo used paper cone cups with a diameter of 3.5 inches and a height of 4 inches.

Conical Cup A

His supply store stopped carrying these paper cones, so he had to start using more standard

paper cups. These are truncated cones (cones with the “pointy end” sliced off) with a top

diameter of 3.5 inches, a bottom diameter of 2.5 inches, and a height of 4 inches.

Cup B

Because some customers said they missed the old cones, Pablo put a sign up saying “The new

cups hold more!” His daughter Letitia wonders if her father’s sign is correct. Help her find out.

a. How much juice can cup A hold? (While cups for juice are not usually

filled to the top, we can assume frozen juice treats would be filled to the

top of the cup.)

b. How much juice can cup B hold?

c. By what percentage is cup B larger in volume than cup A?

50%d. Snow cones have ice filling the cup as well as a hemisphere of ice sticking

out of the top of each cup. How much ice is in a snow cone for each cup?

e. By what percentage is the snow cone in cup B larger than the snow cone in conical cup A?

f. Is Pablo’s sign accurate?
