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.

Answer:
26400cm
Step-by-step explanation:
diameter=84 cm
radius = 84/2=42cm
circumference=2*(22/7)*42=2*22*6=264 cm
distance covered in 100 revolutions=264*100=26400cm
