You can put this solution on YOUR website!
Treat that number given as a radius, and use it to find the circumference.

Distance traveled, approx. circumference 2%2Api%2A9.3%2A10%5E7=2%2A%283.14%29%2A%289.3%29%2A10%5E7
58.4%2A10%5E7
Or if you want two significant figures and in proper scientific notation,
%285.8%29x10%5E8
