Answer

$\approx$ 27,488.94 mi

Work Step by Step

Given A communications satellite forms a circular orbit 375 mi above the earth. If the earth’s radius is approximately4000 mi, to find the distance traveled by the satellite in one complete orbit. The satellite is in the distance from the earth is 4000 + 375 = 4375 mi The perimeter of the circle with radius 4375 mi will be the distance traveled by the satellite in one complete orbit Therefore the distance traveled by the satellite = 2$\pi$r $\approx$ 27,488.94 mi
