You can put this solution on YOUR website! A hot-air balloon travels round the Earth 1km above the surface, following the equator. How much further does it travel than the distance around the equator?
---------------
r = radius of Earth
Equator length (circumference) = 2*pi*r
----
Distance balloon travels = 2*pi*(r+1) = 2*pi*r + 2pi
----
Diff = 2pi km
