Question

A Ferris wheel has a diameter of 90 feet. How far does car travel in one revolution in terms of π?

Answer 1

The distance traveled is given by:

$S = R \alpha$

Where,

R: Ferris wheel radio

α: central angle

The angle for a revolution is:

$1rev = 2\pi rad$

Therefore, substituting values we have:

$S = \frac{90}{2}(2\pi)$

$S = 90 \pi$

Answer:

in one revolution the car travels:

$S = 90 \pi$
