Answer:
2,412,743 km
Step-by-step explanation:
Imagine the path of the moon around the Earth is a circle. Therefore, the Earth is at the center of the circle. Thus, the distance from the Earth (circle's center) to the moon (circle's edge) is the radius. Using the formula for circumference of a circle:
[tex]C=2\cdot\pi\cdot{r}\\C=2\cdot\pi\cdot{384000}\\C=2412743[/tex]
Therefore, the circumference of the path of the moon in one revolution about the Earth is about 2,412,743 km.
