Question
A giant circular wheel has a diameter of 28 metres. In
how many revolutions will the wheel cover a total of 26.4 km?Solution
Radius of the giant wheel = 28 ÷ 2 = 14 metres Circumference of the giant wheel = 2 × π × radius = 2 × (22/7) × 14 = 88 metres So, number of rotations to cover 16.5 km i.e. 16500 metres = 26400 ÷ 88 = 300
