Answer:
7500π mm
Step-by-step explanation:
1. Find out the volume of each penny.
Volume = V=π [tex]r^{2}[/tex]h
In the problem it gives that the diameter of the penny is 20 mm. Therefore the radius is half of that so 10mm. The thickness is the height, which is 1.5 mm.
With that information, we can plug in the values to get
V = π [tex](10)^{2}[/tex](1.5)
V= 150 π mm for each penny.
2. Since there are 50 cents, you know there is 50 pennies. Multiply the volume of each penny by 50 pennies to find out the volume of the roll.
150 π x 50 = 7500π mm[tex]^3}[/tex]
