To find the approximate circumference of a circle, you can use the formula:

\[ C = 2\pi r \]

where \( C \) is the circumference, \( \pi \) is approximately 3.14, and \( r \) is the radius of the circle.

Given a radius \( r = 12 \):

\[ C = 2 \times 3.14 \times 12 \] \[ C = 2 \times 3.14 \times 12 = 6.28 \times 12 = 75.36 \]

So, the approximate circumference of the circle is 75.36.

The correct response is:

75.36.
