Step-by-step explanation:
1 km = 1000 m
1 hour = 3600 s

37.6 km = 37,600 m (still per hour or per 3600 s).

37600/3600 = 10.44444444... m/s
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.
Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
