Which country would be closest to its actual size on a cylindrical map?

A)Australia


B)Ecuador


C)United States


D)Russia

Which country would be closest to its actual size on a cylindrical map?
Actually, it depends on how you construct the cylindrical map projection. It's possible for a cylindrical map projection to be constructed which would display the United States with the least amount of distortion.





However, if we're just assuming that you're talking about the standard Mercator projection, then the answer is B) Ecuador.
Reply:Whichever is closest to the equator. So, I'd say Ecuador. The closer you get to the poles, the larger they look on a cylindrical map. That's why Greenland looks MONSTEROUS on a cylindrical/flat map and not so huge on a globe.
Reply:"b" The farther you get away from the equator in that type of map, the greater the size distortion.
Reply:It has to be Ecuador, because being over the Equator line (like Zaïre, Kenya, some parts of Brazil, Uganda, Brunei, Indonesia) the error committed, by changing from a global surface to a circular surface, is less noticeable than in the other three countries you mentioned, countries that happen to be farther norh from the Equator Line. You see, if you use the wrong projection, a country like the contiguos USA will look much, much larger than Brazil, which, in fact, is not true, for they are just about the same size.
