The sketch is a cross section through the earth, showing two points that have a difference in latitude of angle 0. The mean radius R of the earth is 6.371 106 meters. A nautical mile is defined as 1852 meters exactly. Using these data, calculate how many nautical miles there are between two points on the earth's surface that have the same longitude but have latitudes that differ by 1.000 degree. (Just in case: the definition of angle, in radians, is the arc of a circle it subtends divided by the radius of the circle. A circle is 27 radians or 360.) There are nautical miles between two points with latitudes differing by 1.000. (Enter your answer as a number, without exponents and without units, but with appropriate significant figures.)
