Inside Circle:
r=d÷2 V=pi.r.r.h
r=8÷2 V=(3.14x4x4)x40
r=4cm V=2009.6cm³
Outside Circle:
r=d÷2 V=pi.r.r.h
r=10÷2 V=(3.14x5x5)x40
r=5cm V=3140cm³
3140cm³-2009.6cm³=1130.4cm³

r=20÷2 V=(3.14x10x10)x40
r=10cm V=12,560cm³
Popcorn Lover's:
r=d÷2 V=pi.r.r.h
r=30÷2 V=(3.14x15x15)x20
r=15cm V=14,130cm³
Martha should buy the popcorn lover's one because it has more volume than the jumbo one.Popcorn Lover's volume is 14,130cm³ while Jumbo's 12,560cm³
Great job Michael! It looks neat and organized! Two things you could've added was a video and a link, but overall it was great. Keep up the great work!
