To find the circumference \( C \) of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle. In this case, the diameter \( d \) is 8 kilometers.
Using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 8
\]
Calculating this:
\[
C = 25.12 \text{ kilometers}
\]
Therefore, the estimated circumference is \( 25.12 \) kilometers.
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle. In this case, the diameter \( d \) is 8 kilometers.
Using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 8
\]
Calculating this:
\[
C = 25.12 \text{ kilometers}
\]
Therefore, the estimated circumference is \( 25.12 \) kilometers.
