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.
