A satellite is in an approximately circular orbit 3600 kilometers from Earth surface. The radius of Earth is about 6400 km. What
timofeeve [1]

Answer:

62,832 kilometers

Step-by-step explanation:

The first thing you want to notice is that it's giving you two pieces of one part, if that makes sense. The radius of the earth, and then the distance from the surface of the earth to the orbit. What you want to do is find the circumference of the orbit in relation to the center of the earth. So, as a result, you're going to add those two values together. 6400 + 3600 equals 10,000. Now this is only the radius, but in order to find the circumference, we need the diameter. To find the diameter, you multiply the number by two. 10,000 x 2 is 20,000. Now you multiply this number by pi to find your final answer. This answer is 62,832 kilometers.
