Answer 1

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

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

Given the diameter is 12 inches and using 3.14 as the approximation for \(\pi\):

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

Now, calculate it:

\[ \text{Circumference} = 37.68 \text{ inches} \]

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