Given: Radius of the wheel =35 Covered distance =11km=1100000cm Formula used: The perimeter of the wheel =2πr where r is the radius of the wheel (2πr)×N=D 2πr= Perimeter of wheel N= Number of revolutions D= Covered distance Calculation: According to the formula, 2πr×n=1100000 ⇒2×(22∕7)×35×n=1100000 ⇒220n=1100000 ⇒n=1100000∕220 ⇒n=5000 ∴ The value of n is 5000
