Question

The radius of mars is about 3,390 kilometers. a spacecraft orbits 365 kilometers above the surface of mars. what is the distance the spacecraft travels in a single orbit of mars? round your answer to the nearest kilometer and use 3.14 for π.

Answer 1

We need to find the circumference of the orbit of the spacecraft. Let's first determine the radius of the orbit. From the planet's center, the spacecraft is 3,390 + 365 km away = 3,755 km. 

Circumference = 2πr
C=2(π)(3755 km)
C≈ 23593 km
