Given parameter:

Diameter of the ferris wheel  = 80m

Unknown:

Distance covered in one complete rotation = ?

Solution:

One complete rotation will sweep through the circumference of the wheel.

So,

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

Where r is the radius;

         Radius here is [tex]\frac{80}{2}[/tex]  = 40m

So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]

The distance the wheel sweeps through will be 80π m
