Question
A giant circular wheel has a diameter of 56 metres. In
how many revolutions will the wheel cover a total of 52.8 km?Solution
Radius of the giant wheel = 56 ÷ 2 = 28 metres Circumference of the giant wheel = 2 × π × radius = 2 × (22/7) × 28 = 176 metres So, number of rotations to cover 52.8 km i.e. 52800 metres = 52800 ÷ 176 = 300
