Question

How far does a horse on a Merry-go-round travel in one revolution if he is 6.5 feet from the center? (Use 3 for π)

Answer 1

Answer: The answer is 39 feet.

Step-by-step explanation: Given that a horse on a Marry-go-round is 6.5 feet from the centre. We are to find the distance travelled in one revolution.

Since the horse is 6.5 feet from the centre, so the radius will be

`r=6.5~\textup{feet}.`

Also, given that

`\pi=3.`

One revolution = circumference of the circle of motion.

Circumference is given by

`C=2\pi r=2* 3* 6.5=39~\textup{feet}.`

Thus, the distance travelled is 39 feet.

Answer 2

41 ft

(if pi=3.14 WHICH IT DOESN'T IN THIS PROBLEM so for you who are here for USATest Prep)

Explanation:

C = 2πr = 2(3.14)(6.5) = 40.82

Therefore, to the nearest foot is 41 feet.

To sum it up, USATestPrep say other answer bad. (even though it isn't bad)
