Circumference: 0.75 times pi = 2.356 inches rounded to three decimal places
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 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
Circumference = 2pi*r Circumference = 86pi
