Earth has a radius of 6371 kilometers. A pilot is flying at a steady altitude of 5.6 kilometers above the earth's surface.What is the pilot's distance to the horizon?Enter your answer, rounded to the nearest tenth, in the box.

As the Earth has a radius of 6371 kilometers and pilot is flying at a steady altitude of 5.6 kilometers above the earth's surface. This forms a right angled triangle of perendicular 6371km and hypotenuse of (6371+5.6)km. The pilot's distance to the horizon will be the Base.Hence by pythagoras theorem we have Distance=276.5km rounding of =280km
