Answer:
291131.1 km is the approximate difference in the circumferences.
Step-by-step explanation:
We are given the following in the question:
Radius of earth = 6,371.0 kilometers
Radius of Moon = 1,737.5 kilometers
Circumference of Circle =
[tex]C = 2\pi r[/tex]
where r is the radius of the circle.
Circumference of Earth =
[tex]C_{Earth} = 2\pi (6371.0) = 12742\pi[/tex]
Circumference of Moon =
[tex]C_{Moon} = 2\pi (1737.5) = 3475\pi[/tex]
Approximate difference in the circumference =
[tex]C_{Earth}-C_{Moon}\\=12742\pi - 3475\pi\\=29113.1\text{ km}[/tex]
Thus, 291131.1 km is the approximate difference in the circumferences.
