Answer:

Let r be the radius of the wheel. Then,

Diameter = 84 cm

2r=84

r=42 cm

Circumference of the wheel = 2πr=264cm=2.64m

So, the wheel covers 2.64 meters in one complete revolution.

Total number of revolutions in covering 792 meters =

2.64

792

=300.

Hence, the wheel takes 300 revolutions in covering 792 meters.
