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 ½ in, we can substitute this value into the formula:

C ≈ 3.14 * ½
C ≈ 1.57 inches

Therefore, the approximate circumference of the circle is 1.57 inches.
