The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Using the approximation of π as 3.14, we can substitute the given diameter of 12 inches into the formula:

C = 3.14 * 12 = 37.68 inches.

Therefore, the approximate circumference of the circle with a diameter of 12 inches is 37.68 inches.
