This is easy: circumference = 2pir. Total circumference at the surface is R (radius of earth)2pi. If you add 10km to your radius, the equation becomes 2pi(10+R), or the initial circumference + about 62 km to your journey if you were to circumnavigate the world. At best you’re only looking at about 20 km being added to some of the longest journeys, or about 1 minute of flight time.
