The circumference \( C \) of a circle is calculated using the formula:
\[ C = \pi \times d \]
where \( d \) is the diameter of the circle. For a circle with a diameter of \( \frac{1}{2} \) inch, the circumferene is:
\[ C = \pi \times \frac{1}{2} , \text{inches} \]
Using the approximate value of \( \pi \) as \( 3.14 \):
\[ C \approx 3.14 \times \frac{1}{2} = 3.14 \times 0.5 = 1.57 , \text{inches} \]
Thus, the approximate circumference of the circle is 1.57 inches.
