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