Question

A Ferris wheel has a diameter of 140 ft. There are 40 cars for riders, and they are placed at even intervals around the Ferris wheel. What is the best approximation of how many feet apart the cars are placed? Use 3.14 to approximate for π

Answer 1

Answer: 11 feet

Explanation:

Given: The diameter of the Ferris wheel= 140 ft.

We know that the circumference of the circle is given by :-

`\text{Circumference}=\pi d`, where d is the diameter.

Therefore, the circumference of the Ferris wheel=
`\pi(140)=3.14*140=439.6\ feet`

If there are 40 cars for riders, and they are placed at even intervals around the Ferris wheel.

Then, the distance between the cars=
`439.6/ 40=10.99\approx11\ feet`

Answer 2

The circumference of a Ferris wheel:
C = 2 r π
C = 2 · 70 · 3.14
C = 439.6 ft
439.6 : 40 = 10.99 ≈ 11 ft
Answer:
The cars are placed approximately 11 ft apart.
