The circumference $C$ of a circle is given by the formula:

$C = 2\pi r$

where $r$ is the radius of the circle.

Given that the radius $r$ is 12 feet, we can substitute this value into the formula:

$C = 2\pi \times 12 = 24\pi \text{ feet}$

So, the circumference of the circle is $24\pi$ feet.

Here are 5 related questions:

1. What would the circumference be if the radius were doubled?
2. How do you calculate the area of the same circle?
3. If the diameter of the circle is given, how would you find the circumference?
4. What is the relationship between the radius and the diameter of a circle?
5. How would the circumference change if the radius were 6 ft?

Tip: Always remember that the circumference of a circle is directly proportional to its radius. Doubling the radius will double the circumference.
