The mean radius of the Earth is R=6.38x10^6m. At what distance above the Earth's surface will the acceleration of gravity be 4.905m/s^2?

F_g=(Gmme)/r^2

4.905=6.67x10^-11(5.98x10^24)/r^2

The mass cancel out so that is how I got the above answer.

r=9017663m

Is this the correct answer or would I have to take 9017663m minus the radius of the earth to figure out the distance above the earth's surface. When i did this I got 2637663m Is this the correct answer or is 9017663m?
