To find the circumference of a circle, you can use the formula:
\[
\text{Circumference} = \pi \times \text{diameter}
\]
Given that the diameter is \( \frac{1}{2} \) inch and using \( \pi \approx 3.14 \):
\[
\text{Circumference} = 3.14 \times \frac{1}{2}
\]
Calculating that:
\[
\text{Circumference} = 3.14 \times 0.5 = 1.57 \, \text{inches}
\]
Thus, the approximate circumference of the circle is:
\[
\boxed{1.57} \, \text{in.}
\]
