To find the circumference of a circle using the formula \(C = \pi \times d\) (where \(C\) is the circumference and \(d\) is the diameter), you can plug in the values given.
Given:
- Diameter \(d = 12\) inches
- Approximation for \(\pi = 3.14\)
Now, calculate the circumference:
\[ C = \pi \times d = 3.14 \times 12 \]
Calculating this gives:
\[ C = 3.14 \times 12 = 37.68 \text{ inches} \]
Thus, the approximate circumference of the circle is 37.68 inches.
