Justin's bicycle has 24-inch diameter wheels. Justin pedals his bicycle enough for the

wheels to complete exactly 40 revolutions. To the nearest whole number, how far does

Justin travel?

Respuesta :

Answer:

Total distance covered by bicycle's wheel in  [tex]40[/tex] revolutions is [tex]40\times 75.36=3014.4[/tex][tex]3014 inches[/tex]

Step-by-step explanation:

Diagram of given scenario shown below.

Given That:

Diameter of bicycle Wheel is [tex]24 inches[/tex].

So, Radius of wheel  [tex](r)=\frac{Diameter}{2} = \frac{24}{2} = 12\ inches[/tex]

Wheel has a circular shape.

In order to find the Distance covered in [tex]40[/tex] revolutions we have to find the circumference of the wheel.

  Circumference of circle [tex]=2\pi r[/tex]

Thus, Circumference of wheel  [tex]=2\pi \times12= 24\times \ 3.14[/tex]              { ∵ [tex]\pi =\frac{22}{7}[/tex]≈[tex]3.14[/tex]}

                                                    [tex]=75.36\ inches[/tex]

Therefore,

Total distance covered by bicycle's wheel in  [tex]40[/tex] revolutions is [tex]40\times 75.36=3014.4[/tex][tex]3014 inches[/tex]
