Question

Two satellites are orbiting earth. The path of one satellite has the equation x² + y² = 56 200 000. The orbit of the other satellite is 200 km farther from the centre of the earth. In one orbit how much farther does the second satellite travel than the first satellite?

Answer 1

x^2+y^2=r^2

r^2=56200000
r=7496.66
r2=200
r-r2=7296.66
answer:7296.66
