Question
A giant circular wheel has a diameter of 21 metres. In
how many revolutions will the wheel cover a total of 16.5 km?Solution
Radius of the giant wheel = 21 ÷ 2 = 10.5 metres Circumference of the giant wheel = 2 × π × radius = 2 × (22/7) × 10.5 = 66 metres So, number of rotations to cover 16.5 km i.e. 16500 metres = 16500 ÷ 66 = 250
