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?
Geometry is one of the most challenging concepts for many of our students - was your middle/high schooler able to answer this question? Scroll down to see the solution!
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.
Common core and the integrated maths are awesome for giving students a wide variety of math topics and education that grow more complex and detailed each year, but often times geometry becomes a subset of math that students grow to dread or hate because it's so difficult to conceptualize, visualize or find applicable to daily life.
Here at Mathnasium, though, problem solving and geometry are skills we regularly delve into with our students, and our math tutors are more than happy to help if these concepts are causing any trouble on homework or studying for a test.
