Jill and Marcy go to an ice cream store where they have the option of getting a smoothie in either a cylindrical or rectangular
k0ka [10]

Answer: Jill got the larger smoothie and its volume is 1609.14 cubic cm.

Step-by-step explanation:

Since we have given that

Jill purchased the cylindrical container.

Height of container = 8 cm

Radius = 8 cm

So, volume of cylindrical container would be

\pi r^2h\\\\=\dfrac{22}{7}\times 8\times 8\times 8\\\\=1609.14\ cm^3

Marcy purchased the rectangular container.

Height of container = 8 cm

Width = 8 cm

Length = 8 cm

so, volume of rectangular container would be

l\times b\times h\\\\=8\times 8\times 8\\\\=512\ cm^3

Hence, Jill got the larger smoothie and its volume is 1609.14 cubic cm.
