Find the number of regular (statute) miles in 4 nautical miles to the nearest hundredth of a mile. (Use 4,000 miles for the radius of the earth.) (If a central angle with its vertex at the center of the earth has a measure of 1', then the arc on the surface of the earth that is cut off by this angle (known as the great circle distance) has a measure of 1 nautical mile.) I used the S/r so 4nautical miles/4000 (radius) and get the answer: 0.001. The answer appears to be incorrect. Can somebody please help me figure out how to work this problem? Thank you!
