To find the 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.

Given that the radius \( r \) is 12, we can substitute that into the formula:

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

Calculating that step-by-step:

  1. Calculate \( 2 \times 3.14 = 6.28 \)
  2. Then multiply that result by 12:

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

So the approximate circumference of the circle is 75.36.

The correct response is 75.36.
