The diameters of front and rear wheels of a tractor are 80 cm and 2 m respectively. Find the number of revolutions that rear wheel will make in covering a distance in which the front wheel makes 1400 revolutions.
560 revolutions.
Solution:
Circumference of circle =
Diameter of front wheel = 80 cm
Radius =
Diameter of rear wheel = 2m = 200 cm
Radius =
We know that distance covered in one revolution =
distance covered by front wheel in 1400 revolution =
Let rear wheel take x revolutions = x × 2π(100)
According to question
Rear wheel will make 560 revolutions.
