Question

A school van has wheels of diameter 84cm. Find the distance covered by the van in 100 revolutions. Pls tell the answer fast

Answer 1

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 2

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
