Answer 1

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

\[
\text{Circumference} = \pi \times \text{Diameter}
\]

Given that the diameter is 12 inches and using 3.14 to approximate \(\pi\):

\[
\text{Circumference} = 3.14 \times 12
\]

Calculating that:

\[
\text{Circumference} = 3.14 \times 12 = 37.68 \text{ inches}
\]

So, the approximate circumference of the circle is **37.68 inches**.
