Answer 2

1297.37 feet.

Explanation:

Given:

The carousel at a local theme park has a diameter of 32 feet.

Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.

Question asked:

What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.

Solution:

First of all we will find the radius of the carousel:-

Diameter = 32 feet

Radius, r =
`(Diameter)/(2) =(32)/(2) =16\ feet`

Now, we will find distance covered by the carousel in one ride that means its circumference;

`Circumference\ of \ the \ circle=2\pi r`

`=2*(22)/(7) *16\\ \\ =(704)/(7) \\ \\ =100.571\ feet`

In 1 minute, number of revolution taken by carousel = 4.3

As each ride last for 3 minutes:-

In 3 minutes, number of revolution taken by carousel = 3
`*` 4.3 = 12.9

In 1 revolution, distance covered by carousel = 100.571 feet

In 12.9 revolution, distance covered by carousel = 100.571
`*` 12.9

= 1297.365 feet

Thus, the maximum distance riders travel in one full ride is 1297.37 feet.
