Answer:
25748 km
Explanation:
The distance at which astronauts travel can be obtained by calculating the Circumference of the circle.
Circumference of a circle = 2πr ; π = 3.14
Radius = 4100 km
Circumference of a circle = 2 * 3.14 * 4100
Circumference of the circle = 25748 km
Hence, astronauts travel a distance of 25748 km
