Answer 1

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

\[ C = 2\pi r \]

where \( C \) is the circumference and \( r \) is the radius of the circle.

In this case, you provided a diameter of 12 feet. The radius is half of the diameter:

\[ r = \frac{d}{2} = \frac{12 \text{ ft}}{2} = 6 \text{ ft} \]

Now, substitute the radius into the circumference formula:

\[ C = 2 \times 3.14 \times 6 \]

Calculating that:

\[ C = 2 \times 3.14 \times 6 = 37.68 \text{ ft} \]

So, the circumference of the circle is approximately **37.68 ft**.
