To find the circumference of a circle, the formula is:

$C = 2 \pi r$

Where:

• $C$ is the circumference,
• $\pi$ is approximately 3.14,
• $r$ is the radius of the circle.

Given that the radius $r$ is 6 feet, we can substitute into the formula:

$C = 2 \times 3.14 \times 6$

Calculating:

$C = 37.68 \text{ feet}$

Thus, the circumference of the circle is 37.68 feet.

Here are five related questions:

1. What is the area of the circle with a radius of 6 feet?
2. How does the circumference change if the radius is doubled?
3. How can we find the diameter of the circle, and how does it relate to the circumference?
4. What would the circumference be if we used a more precise value of $\pi$?
5. How does the formula for the circumference of a circle compare to the formula for the perimeter of other shapes?

Tip: Remember that the diameter of a circle is always twice the radius!
