An aircraft circumnavigates the earth 10 km above the earth's surface. If it completes one full circle, the distance covered will be _____ greater than the circumference of the earth. (Assume earth radius is 3280 km, and π = 3.14)
Select an option to attempt
Correct Answer: Option A
Explanation
Extra circumference when flying 10 km above Earth's surface:Circumference of Earth at surface:Circumference at altitude h:Extra distance covered:Key insight: The extra circumference depends ONLY on the altitude (h), not on Earth's radius. Regardless of the actual radius, each additional km of radius adds exactlykm of circumference.Answer: 62.8 km (Option 1).
