A jet is circling an airport control tower at a distance of 20.6 km. An observer in the tower watches the jet cross in front of the moon. As seen from the tower, the moon subtends an angle of 9.26x10-3 radians. Find the distance traveled (in meters) by the jet as the observer watches the nose of the jet cross from one side of the moon to the other.

197.76 m

Explanation:

r = Radius of the path = 20.6 km =

= The angle subtended by moon =

Distance traveled is given by

The distance traveled by the jet is 197.76 m

the answer would be a
