1. The problem asks to find the circumference $C$ of a circle given its diameter $d = 22$ yd. 2. The formula for the circumference of a circle is: $$C = \pi d$$ where $\pi$ is approximately 3.1416. 3. Substitute the given diameter into the formula: $$C = \pi \times 22$$ 4. Calculate the circumference: $$C = 22\pi$$ 5. To get a numerical approximation, multiply 22 by 3.1416: $$C \approx 22 \times 3.1416 = 69.1152$$ 6. Therefore, the circumference of the circle is approximately 69.12 yd. This means if you walked around the circle, you would cover about 69.12 yards.
