Answer:
25 times
Step-by-step explanation:
Circumference of the wheel = 2πr
= 22/7 × 14 × 2
= 88 cm
Distance = 22 m
= 2200 cm
Revolutions = distance/circumference
=2200/88
= 25 revolutions

To find : How many times will a wheel of radius 14 cm have to rotate to cover a distance of 22 m?
Solution :
A wheel of radius 14 cm
Circumference of the wheel is C= 2πr
C=88 cm
It cover a distance of 22 m.
Convert into cm,
1 m = 100 cm
22 m=2200 cm
The number of times wheel rotate is given by,
REVOLUTIONS=25
Therefore, 25 times will a wheel rotate to cover a distance.
