inches

The formula to calculate the circumference of a circle is:

Circumference = Ο€ x diameter

Given that the diameter of the button is 4 inches and Ο€ = 3.14, we can substitute these values into the formula:

C = 3.14 x 4
C = 12.56 inches

Therefore, the circumference of the campaign button is approximately 12.56 inches.
