The formula for the circumference \( C \) of a circle is given by:
\[ C = 2 \pi r \]
where \( r \) is the radius of the circle.
In this case, the radius \( r \) is 3 feet. Plugging in the value:
\[ C = 2 \times 3.14 \times 3 \]
Calculating this step by step:
- Multiply \( 2 \times 3.14 = 6.28 \).
- Then multiply \( 6.28 \times 3 = 18.84 \).
Therefore, the circumference of the circle is approximately:
\[ C \approx 18.84 \text{ feet} \]
So the estimated circumference to the hundredths place is 18.84 feet.
