It clearly says " 2,500 miles in diameter" which makes it 1,250 mile radius. pi * 1250 *1250 = 4,908,738 square miles or ~5 million square miles. That is < 10

pi * 1250 *1250 = 4,908,738 square miles or ~5 million square miles.
That is < 10% of the earths land mass.
- alexilliamson 7y agoYeah this is the error in the parent calculation
- swsieber 7y agoIt also clearly says "2500 radius circle" in the article title, and the submission title. The article is fast and loose with diameter vs radius later on as well. I can't blame the original commenter for using it as a radius when that's in the title. But I agree, it's actually the diameter and changes the math a lot.
- humblebee 7y agoThe distance from Mumbai India to Osaka Japan is ~4000 miles. Both of which are clearly inside the circle. What are you using to assert that the 2500 mile number is the diameter?
- wongarsu 7y agoThis actually fits with the visual impression you get from the map. It's clearly far less than 50% of the inhabitable land mass
- Abimelex 7y agoyou also need to map the circle firs to the surface, a circle on a world map is not the same as a circle on the globe.
