Problem of the Week - Middle School - March 28, 2021 to April 3, 2021

Middle School: 

Question: An unroasted marshmallow has a volume of 0.25π cubic inches. After Andrew roasts the marshmallow over a campfire, its volume is 150% its original volume. What is the post-roast volume of the marshmallow? 

Answer: 0.375π cubic inches

Solution:  To find 150% of 0.25π, we can multiply the 1.5 by  0.25 and then by π: 1.5 multiplied by 0.25 is 0.375, and 0.375 multiplied by π is 0.375π. So, the volume of the roasted marshmallow is 0.375π cubic inches.
