The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circle is 12 in, we can substitute this value into the formula:
C ≈ 3.14 * 12
C ≈ 37.68
The approximate circumference of the circle is 37.68 inches.
