Answer :
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
Penny:
diameter = 19.05 mm
height = 1.52 mm
Standard Roll of pennies:
number of coins = 50
volume = ?
Step 02:
Volume of a cylinder
V = π r ² h
V = 50 * 3.14 * (19.05 mm / 2)² * 1.52 mm
V = 21650.76mm³
The answer is:
The volume of the roll of pennies is 21650.8 mm³
