Cylinder Volume and Volume Problems




Jumbo
V= π.r.r.h
V= 3.14.10.10.40
V= 12 560cm³


Popcorn Lover's
V= π.r.r.h
V= 3.14.15.15.20
V= 14 130cm³

I think that Martha should get the Popcorn Lover's one because it has more volume to get more popcorn.
Inside:
V= π.r.r.h
V= 3.14 .0.4 .0.4 .10
V= 5.024cm³

Outside:
V= π.r.r.h
V= 3.14. 0.5 . 0.5 . 10
V= 7.85cm³

7.85 - 5.024=2.826m³

  1. Great Job Justin! I think you blew up the blog a bit, but your post was great. You should try to make it a bit more organized and neater but other than that, great job!

  2. Good job Justin! Your blog was simple and your pictures were clear so they could be read. You also included a website and 2 videos which I like. Although your videos are a bit too big. Other than that, nice post!
