To find the circumference of a circle, you can use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference, \( \pi \) is approximately 3.14, and \( d \) is the diameter of the circle.
Given the diameter \( d = 8 \) kilometers:
\[ C = 3.14 \times 8 \]
\[ C = 25.12 \]
So, the estimated circumference of the circle is **25.12 kilometers**.
\[ C = \pi \times d \]
where \( C \) is the circumference, \( \pi \) is approximately 3.14, and \( d \) is the diameter of the circle.
Given the diameter \( d = 8 \) kilometers:
\[ C = 3.14 \times 8 \]
\[ C = 25.12 \]
So, the estimated circumference of the circle is **25.12 kilometers**.
