A) 1890m
B) 1980m
C) 1900m
D) 1800m
Correct Answer: B
Solution :
One revolution made by the wheel of the car is equal to the circumference of the wheel. Given diameter of the wheel, d = 63 cm \[\text{1173}0=\text{2}\times \text{3}\times \text{5}\times \text{17}\times \text{23}\]The radius, \[\therefore \] \[=\text{17}\times \text{23}=\text{391}\]Circumference, \[=\text{2}\times \text{3}\times {{\text{5}}^{\text{2}}}\times \text{7}\times \text{l7}\times \text{23}=\text{41}0\text{55}0\] \[\pi \] \[\frac{22}{7}\] \[\frac{22}{7}\] The distance travelled by the car in one revolution = 1.98 m The distance travelled by the car in 1000 revolutions \[\pi \]
