The formula for the circumference \( C \) of a circle is given by:
\[ C = 2 \pi r \]
where \( r \) is the radius of the circle. Given that the radius \( r \) is 7 ft, we can substitute this value into the formula. Using \( \pi \) as 3.14, the calculation becomes:
\[ C = 2 \times 3.14 \times 7 \]
Calculating this step by step:
- Calculate \( 2 \times 3.14 = 6.28 \)
- Then multiply by \( 7 \):
\[ C = 6.28 \times 7 = 43.96 \]
Thus, the circumference of the circle is
\[ \boxed{43.96 \text{ ft}} \]
