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.
