Question

A Ferris Wheel is set up at the carnival it has a diameter of 45 feet. What is the total circumference if the ferris wheel makes 4 rotations around?

Answer 1

The circumference is 565.2 feet when the ferris wheel makes 4 rotations.

Explanation:

Given that the diameter of the wheel is 45 feet.

That is:

`d = 45\ feet`

We have to find the radius first

`r = (d)/(2) = (45)/(2) = 22.5\ feet`

The circumference of the circular wheel for one rotation will be:

`C = 2\pi r`

And for four rotations' circumference the circumference of one rotation will be multiplied with 4.

`C = 2 * 3.14 * 22.5\\C = 141.3\ feet`

Total circumference:

`C_T = 4C\\= 4 * 141.3\\=565.2\ feet`

Hence,

The circumference is 565.2 feet when the ferris wheel makes 4 rotations.
