    .....Also for the second problem i attained 59 0000m as my answer ..i dont know if it's wrong cause Meneer's answer was different from mine

    When someone is on the ground then they go up a mountain 6000m do we take that 60000m and add it to the radius of the earth ... If so why do we do that because they are practically still on earth
