QuestionQuestion 22 (1 point) The height, hh, in metres, above the ground of a car as a Ferris wheel rotates can be modelled by the function h(t)=16cos(πt120)+18h(t)=16 \cos \left(\frac{\pi t}{120}\right)+18, where tt is the time, in seconds. What is the radius of the Ferris wheel? a) 16 m b) 8 m c) 9 m d) 18 m

Studdy Solution
Determine the radius of the Ferris wheel:
The amplitude of the cosine function represents the radius of the Ferris wheel. Therefore, the radius is 16 meters.
The radius of the Ferris wheel is 16 \boxed{16} meters.
