An American penny's diameter is 19.05mm. The formula for the circumference of a circle is C = π * d. Using π ≈ 3.14 gives a circumference of 59.82 mm or 5.982 cm.
It has a circumference of 12.88 cm
Diameter in cm = circumference/pi
Circumference of the circle = pi*17.6 cm
Circumference of the circle = pi*17.6 cm
circumference = pi*46 cm
A US copper penny is exactly 2 cm wide.
