Question 1906Navigation General70% to pass
For navigational purposes, each great circle on the Earth has a length of _______________.
AI Explanation
The correct answer is C) 21,600 miles.
The length of each great circle on the Earth is approximately 21,600 miles. This is because a great circle is the largest possible circle that can be drawn on the surface of a sphere, and the circumference of the Earth is approximately 24,900 miles. Dividing the Earth's circumference by 360 degrees gives the length of each great circle.
The other answer choices are incorrect because they do not accurately represent the length of a great circle. 3,600 miles is too short, 12,500 miles is too long, and 5,400 miles is also too short for the length of a great circle on the Earth's surface.
