The formula to calculate the circumference of a circle is given by:
\[ C = 2\pi r \]
where \( C \) is the circumference and \( r \) is the radius of the circle.
Given that the radius \( r = 12 \) and using \( \pi \approx 3.14 \), the calculation would be:
\[ C = 2 \times 3.14 \times 12 \]
Calculating this step-by-step:
- \( 2 \times 3.14 = 6.28 \)
- \( 6.28 \times 12 = 75.36 \)
So, the approximate circumference of the circle is 75.36.
Thus, the correct response is 75.36.
