To calculate the area of the circle, we need to find the radius first. The diameter of the circle is given as 22 ft, so the radius (r) is half of the diameter:
\[ r = \frac{diameter}{2} = \frac{22 , \text{ft}}{2} = 11 , \text{ft} \]
Now we can use the formula for the area of a circle:
\[ A = 3.14 \times r^2 \]
Substituting in the value for the radius:
\[ A = 3.14 \times (11 , \text{ft})^2 \]
Calculating \(11^2\):
\[ 11^2 = 121 \]
Now substituting that back into the area formula:
\[ A = 3.14 \times 121 \]
Calculating this gives:
\[ A = 379.94 , \text{ft}^2 \]
So, the area of the circle is approximately:
\[ \boxed{379.94} , \text{ft}^2 \]
