To find the circumference of a circle, you can use the formula:
\[ C = 2\pi r \]
where \( r \) is the radius of the circle. In this case, the radius is given as 11 ft.
1. Plug in the radius into the formula:
\[ C = 2 \pi (11) \]
2. Calculate it:
\[ C = 22\pi \]
3. Using \( \pi \approx 3.14 \):
\[ C \approx 22 \times 3.14 = 69.08 \, \text{ft} \]
Rounding to the nearest tenth:
\[ C \approx 69.1 \, \text{ft} \]
So, the circumference of the circle is **69.1 ft**.
\[ C = 2\pi r \]
