To find the distance to walk all the way around the circular path, we first need to understand the relationship between the diameter and the circumference of a circle. The formula for the circumference \( C \) of a circle is given by:

\[ C = \pi \times d \]

where \( d \) is the diameter of the circle.

Given that the sidewalk through the middle is half a mile long, this means the diameter of the circular path is 0.5 miles.

Now, we can calculate the circumference using the formula:

\[
C = \pi \times 0.5
\]

Assuming \( \pi \approx 3.14 \):

\[
C \approx 3.14 \times 0.5 = 1.57 \text{ miles}
\]

Rounding to one decimal place gives us:

\[
C \approx 1.6 \text{ miles}
\]

Therefore, the distance to walk all the way around the circular path is approximately **1.6 miles**.
