Answer 1

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

\[ C = 2 \pi r \]

where \( C \) is the circumference and \( r \) is the radius.

Given that the radius \( r = 12 \) and using \( \pi \approx 3.14 \):

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

Calculating this:

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

So the correct answer for the approximate circumference of a circle with a radius of 12, using 3.14 for π, is:

75.36
