The circumference of the circle is approximately
\(18.85 \, \text{ft}\).

The circumference
(\(C\)) of a circle is given by the formula:


\[ C = 2 \pi r \]

where:

-
\(C\) is the circumference,

-
\(\pi\) is a constant (approximately 3.14159),

-
\(r\) is the radius of the circle.

Given that the radius
(\(r\)) of the circle measures 3 ft, you can use the formula to find the circumference:


\[ C = 2 \pi * 3 \, \text{ft} \]


\[ C \approx 6 \pi \, \text{ft} \]

If you want a numerical approximation, you can substitute the value of
\(\pi\) (approximately 3.14159) into the equation:


\[ C \approx 6 * 3.14159 \, \text{ft} \]


\[ C \approx 18.84954 \, \text{ft} \]
