Before 1982 U.S pennies were made of solid copper. As the price of copper rose,the U.S mint switched to a composition that is 97.5% zinc and 2.5% copper. A penny minted after 1982 is 19 mm in diameter and 1.6 mm thick.
What is the volume of a penny in mL?
volume = pi*r2*h
r = (19/2) mm and I suggest you change this to cm by dividing by 10 so (18/20) cm radius.
height is 1.6 mm or 0.16 cm.
Using the cm measurements, the volume will be in cubic centimeters, or cc, and that is the same as mL.
