The diameter of the circle is 1/2 inches.

Using the formula for the circumference of a circle, we can calculate the circumference:

Circumference = π * diameter

Approximating π as 3.14, we have:

Circumference = 3.14 * (1/2)

Circumference = 3.14 * 0.5

Circumference ≈ 1.57 inches

Therefore, the approximate circumference of the circle with a diameter of 1/2 inch is 1.57 inches.
