Circumference: 0.75 times pi = 2.356 inches rounded to three decimal places
Diameter of an Australian penny (no longer currency) is 1 and 3/16".
0.75"
The formula for the circumference of a circle is 2.pi.r where r= the radius, since the diameter is 2.r (two times the radius),the circumference will be pi.diameter. pi=3.14159... so for a diameter of 34mm the circumference=pi.34=106.8mm
An American pennys diameter is 19.05mm, and using the formula C = Pi*2r = Pi*d. in circumference it is approximately 59.84 mmThe circumference of a [UK] penny is 63.8 mm approx.
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.

The diameter of a U.S. penny is 19.05 millimeters, which is equivalent to 0.75 inches in customary units.
The diameter of a U.S. penny is 19.05 millimeters (0.75 inches), and its thickness, or width, is approximately 1.52 millimeters (0.0598 inches). The penny is made primarily of zinc, with a copper plating. This size has remained consistent since the penny was redesigned in 1909.
The size of the penny is very important. The weight of it is 2.500 grams exactly. The diameter is 0.750 inches or 19.05 mm or 1.905 centimeters.
A PENNY coin has a Diameter of exactly 1&3/16ths Inches which is same as 1.1875 inch. The foregoing applies to a British penny. A US 1 cent piece is 19.05mm (.75 inches) in diameter, 1.55mm thick, and weighs 2.5 grams
A U.S. penny has a diameter of 19.05 millimeters (0.75 inches) and a thickness of 1.52 millimeters (0.0598 inches). Its size has remained consistent since the introduction of the Lincoln penny in 1909.
