Question

A Ferris wheel has a diameter of 86 ft.

Answer 1

Answer:

$86\pi\ feet$ each car travel in one revolution in terms of π .

270.04 feet each car travel in one revolution .

Step-by-step explanation:

Formula

$Circumference\ of\ a\ circle = 2\pi r$

Where r is the radius of the circle .

As given

A Ferris wheel has a diameter of 86 ft.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{86}{2}$

                   = 43 feet

Thus

$Circumference\ of\ a\ circle = 2\times 43 \pi$

$Circumference\ of\ a\ circle = 86\pi\ feet$        

Therefore $86\pi\ feet$ each car travel in one revolution in terms of π .

Now

π = 3.14

$Circumference\ of\ a\ circle = 2\times 43\times 3.14$    

                                                     = 270.04 feet

Therefore 270.04 feet each car travel in one revolution .
