Answer:

Explanation:

The circle's circumference is modeled by the equation C=2πr. R is the readius of the circle, and pi is the symbol for the number 3.1419...... and it's infinite. So if C=2π(2), the answer for the circumference of a circle with a radius of 2 km would be 4π km, or approximately 12.57 km.
