A satellite in a circular orbit 879.4 mi above the earth makes one complete orbit every 83.42min. What is its linear velocity? Use 3963 mi for the length of the radius of the earth.

the radius of your satellite's orbit is 3963+879.4 = 4842.4
C = 2pi*r = 30425 mi
velocity = 30425mi/83.42min = 364.73mi/min
