Answer:
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Step-by-step explanation:
Given : diameter of a penny is 19.05 millimeters and the width of each penny is 1.52 millimeters.
To find : volume of the roll of pennies.
Solution : We have given that
Diameter of a penny = 19.05 millimeters.
Width of each penny = 1.52 millimeters.
Volume of cylindrical roll of penny = pi * r² * h
Where, r = radius , h =height
Radius = [tex]\frac{Diameter}{2}[/tex]
Radius= [tex]\frac{19.05}{2}[/tex].
Radius = 9.525 mm
Plugging the values of r , h and pi = 1.14.
Volume of cylindrical roll of penny = pi * r² * h
Volume of cylindrical roll of penny =3.14 * (9.525)² * 1.52
Volume of cylindrical roll of penny = 433.02 mm³
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Therefore, Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
