Question

diameter of the wheel of a car is 70 cm how many Revolution will it make to travel 1.65 kilometre​

Answer 1

Step-by-step explanation:

perimeter of wheel=2πr cm

r=70/2=35

p =2×22/7×35

=2×22×5

=44×5=220

p=220cm

Revolution=cm/p

1km=100000cm

1.65km=1.65×100000=165000cm

R=165000/220

=750

therefore 750revolutions will want for travel 1.65 kilometers.
