If a circular wheel covers a distance of 9240 metres in 105
revolutions, find the diameter of the wheel. (Use π = 22/7)Solution
ATQ,
Distance = 9240 metres
Circumference = 9240 ÷ 105 = 88 metres
Let radius be x metres
Circumference = 2πr
ATQ:
88 = 2 × (22/7) × x
x = 14
Diameter = 2 × 14 = 28 metres
