1. **State the problem:** We have a circle with a diameter of 22 yards and need to find the area $A$ of the circle in square yards.
2. **Formula used:** The area of a circle is given by $$A = \pi r^2$$ where $r$ is the radius.
3. **Find the radius:** The radius is half the diameter, so $$r = \frac{22}{2} = 11 \text{ yd}$$
4. **Calculate the area:** Substitute $r=11$ into the area formula:
$$A = \pi (11)^2 = \pi \times 121 = 121\pi \text{ yd}^2$$
5. **Approximate the area:** Using $\pi \approx 3.1416$,
$$A \approx 121 \times 3.1416 = 380.132 \text{ yd}^2$$
**Final answer:**
$$A = 121\pi \approx 380.13 \text{ yd}^2$$
