Aferris wheel has 20 cars that are equally spaced around the circumference of the wheel. the wheel rotates so that the car at the bottom of the ride is replaced by the next car. by how many degrees does the wheel rotate? the ferris wheel rotates ° between successive cars being at the bottom.

The Ferris wheel rotates 18° between successive cars being at the bottom.

Explanation:

 Angle inside a circle = 360°

 No of cars in a Ferris wheel = 20

 When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.

  Angle between two consecutive cars of Ferris wheel = 360/20 = 18°

 The Ferris wheel rotates 18° between successive cars being at the bottom.
