### Example Problem:
*Problem*: Solve for \( x \) in the equation \( 2x + 3 = 11 \).

### Expected Format:
*Step 1*: Subtract 3 from both sides of the equation.  
<thinking>Subtracting 3 from both sides should isolate the term with \( x \). Am I confident this is the correct first step? Yes, because it simplifies the equation to \( 2x = 8 \).</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Divide both sides by 2.  
<thinking>Dividing by 2 will solve for \( x \). This is a straightforward division. Is there any reason to doubt this step? No, it should give \( x = 4 \).</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Verify the solution by substituting \( x = 4 \) back into the original equation.  
<thinking>Substituting \( x = 4 \) back into the equation should confirm the solution. Does \( 2(4) + 3 = 11 \)? Yes, it does, so the solution is verified.</thinking>  
*Step 3 Confidence Score*: 1.00

Question: Consider a circle with its center on the x-axis and passing through the points (0,6) and (0,-6). What is the minimum possible length of the arc of the circle that lies below the x-axis?
Answer: ## Step 1:  The problem involves finding the minimum possible length of the arc of a circle that lies below the x-axis. The circle's center is located on the x-axis, and it passes through the points (0,6) and (0,-6).
## Step 2:  Given the symmetry of the circle and the fact that the two points are equidistant from the x-axis, we can infer that the center of the circle is at the origin (0,0).
## Step 3:  The radius of the circle can be determined by the distance from the center to either of the points (0,6) or (0,-6), which is 6 units.
## Step 4:  Now, we need to find the length of the arc that lies below the x-axis. Since the circle is symmetric about the x-axis, the arc below the x-axis is a semicircle.
## Step 5:  The length of the arc is given by the formula for the circumference of a circle divided by 2, as it is a semicircle: $\frac{1}{2} \times 2\pi r$, where $r$ is the radius of the circle.
## Step 6:  Substituting the value of the radius ($r=6$) into the formula, we get the length of the arc as $\frac{1}{2} \times 2\pi \times 6 = 6\pi$.
## Step 7:  Therefore, the minimum possible length of the arc of the circle that lies below the x-axis is $6\pi$.

The final answer is: $\boxed{6\pi}$
