Question

The Merry Go Round at the State Fair has a diameter of 82 feet and makes 15 revolutions per ride. How far would someone travel during one ride?

Answer 1

Answer:

About 1177.2 meter

Step-by-step explanation:

Given:

Diameter of Merry Go Round = 82 feet

Total revolution in one round = 15

Question asked:

How far would someone travel during one ride ?

Solution:

Diameter = 82 feet, radius = half of diameter,r = $\frac{82}{2} = 41$

Circumference of a circular Merry Go Round = $2\pi r$

                                                                          = $2\times3.14\times41 = 257.48$

By applying unitary method:

In one round of Merry Go Round someone can travel = 257.48

In 15 rounds of Merry Go Round someone can travel = $257.48\times15$

                                                                                        = 3862.2 feet

Now convert it into meter,

1 feet = 0.30 meter (approx)

3862.2 feet = $0.30\times3862.2 = 1177.199m (approx)$

Therefore, about 1177.2 meter can be traveled by someone in one ride.
