The distance traveled is given by:
[tex] S = R \alpha [/tex]
Where,
R: Ferris wheel radio
α: central angle
The angle for a revolution is:
[tex] 1rev = 2\pi rad [/tex]
Therefore, substituting values we have:
[tex] S = \frac{90}{2}(2\pi) [/tex]
[tex] S = 90 \pi [/tex]
Answer:
in one revolution the car travels:
[tex] S = 90 \pi [/tex]
