The diameters of the front and rear wheels of a tractor are 80 cm and 2 m respectively. Find the number of revolutions that a rear wheel makes to cover the distance which the front wheel covers in 800 revolutions.
Radius of front wheel =40cm=25 m
Circumference of the front wheel =(2π×25) m=4π5
Distance covered by the front wheel in 800 revolutions =(4π5×800)m=(640π) m
Radius of the rear wheel = 1 m
Circumference of the rear wheel =(2π×1)=2π m
Therefore, Required number of revolution =Distance covered by the front wheel in 800 revolutionsCircumference of the rear wheel=640π2π=320
