right?

amistre64 · Answer

well, lets use the 2pi r version since we can define the radius more readily from the given information

anonymous · Answer

ok

amistre64 · Answer

define the radius to the satellite with the given information, what do we get?

anonymous · Answer

40192?

amistre64 · Answer

7000
+6400
------
13400
