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,
  • \( r \) is the radius of the circle.

In this case, the radius \( r \) is 12. Plugging the values into the formula, you get:

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

Now, calculate it step by step:

  1. Calculate \( 2 \times 3.14 \): \[ 2 \times 3.14 = 6.28 \]

  2. Now multiply \( 6.28 \) by the radius \( 12 \): \[ 6.28 \times 12 = 75.36 \]

Thus, the approximate circumference of the circle is 75.36.

So, the correct answer is: 75.36
