Question
If a wheel covers a distance of 2200 cm in 7 rotations,
then the diameter of the wheel is?Solution
Distance covered in 7 rotations = 2200cm Distance covered in 1 rotations = 2200/7 c m ∴ Distance covered in 1 rotation = circumference of the wheel 2πr = 2200/7cm 2r (diameter) = (2200 × 7)/(7×22) = 100cm = 1m
