Question

The diameter of a bicycle wheel is 63 cm. How many complete rotations does the
wheel make while covering 1.98 kms? (Hint: 1​

Answer 1

Step-by-step explanation:

By considering pi=22/7

diameter of the wheel = 63 cm

circumference of the wheel = pi*diameter = 22/7*63 = 198 cm

means for one turn the wheel has to cover 198 cm.

So the total number of turns taken by the wheel to cover 19.8 km = (19.8 km)/(198 cm) = (19.8*1000*100)/198 = 10000

So the answer is 10000 turns
