Answer:
10 Revolutions
Step-by-step explanation:
Given, radius of the wheel, r = 70 cm = 0.7 m
We know that the distance covered in one revolution of the wheel is given by its circumference.
∴ Circumference =2 πr = 2 × 22 /7 × .7 = 4.4m
Hence, the distance covered in one revolution of the wheel is 4.4 m.
Number of revolutions of the wheel needed to cover a distance
of 44m = 44/4.4 = 10
