Step-by-step explanation:
diameter of the car wheel = 70cm
Radius = 70/2 = 35 cm
circumference of the car wheel = 2πr
= 2× 22/7× 35cm
= 220 sq. cm
distance travel by car wheel = 1.65 km
converted km in cm = 1.65 × 100000cm
= 165000cm
revolution will make to travel by car wheel
= 165000/220
= 750 revolution
