The radius of a circle measures

6ft

. What is the circumference of the circle?

Use

3.14

for

π

, and do not round your answer. Be sure to include the correct unit in your answer.

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**.

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!
