Answer:
Radius=d/2=70/2=35cm
Perimeter of circle=2πr=2×22/7×35
2×22×5=220cm
Number of round=165×1000×100/220×100=15×50=750

Answer:
Answer:
750 revolutions
Step-by-step explanation:
the diameter of a wheel of a car = 70 cm
circumference of a wheel = πd
= 22/7*70
= 220cm
convert cm to Km = 220/100000
length of the journey = 110
no of revolutions = distance/ circumference
= 1.65/220/100000
= 1.65×100000÷220
= 750
750 revolutions are needed to cover 1.65 km
