The formula to calculate the circumference of a circle is:
Circumference = π x diameter
Given that the diameter of the button is 4 inches and π = 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.
