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

$C = 2 \pi r$

Given that:

• The radius $r = 3 \, \text{feet}$
• The approximation $\pi = 3.14$

We can substitute the values into the formula:

$C = 2 \times 3.14 \times 3$

Let me calculate this.The estimated circumference of the circle is $18.84 \, \text{feet}$, rounded to the hundredths place.

Would you like more details or have any further questions?

Here are some related questions to explore:

1. How would the circumference change if the radius was doubled?
2. What would be the area of this circle using the same value of $\pi$?
3. How does the formula for circumference relate to the formula for the area of a circle?
4. Can you find the diameter of the circle from the given radius?
5. How would the result differ if we used a more precise value of $\pi$ (such as 3.1416)?

Tip: Remember, the diameter of a circle is twice the radius, and you can directly use the diameter to find the circumference using $C = \pi \times d$.
