Answer 2

Given,

Radius of the wheel = 28 cm

Total distance = 352 m

π = 22/7

To find,

The number of revolutions that the wheel have to rotate in order to travel the total distance.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Circumference of the wheel = 2 × 22/7 × 28 = 176 cm = 1.76 metre

So, the wheel will travel a distance of 1.76 metre by one rotation.

Number of rotations needed to complete the total distance = 352/1.76 = 200

Hence, the wheel have to rotate for 200 times
