Answer:

37.7in.

Explanation:

The circumference of a circle is:
$C=2\pi r$

However, the question wants us to use 3.14 instead of
$\pi$ .

We are given 12 inches as the diameter of the circle.

We want the radius, which is half of the diameter.

The radius of the circle is 6 inches.

Now that we have the radius, we plug and chug.

$C=2*3.14*6in.\\C=6.28*6in.\\C=37.68in.\\$

However, the question wants us to round the answer to the nearest tenth.

Therefore, the new answer is:
37.7in.
