A wheel revolves 1254 times in travelling a distance of 2kms 5 hectometers and 8 meters .find the circumference of the wheel .
1 km = 1000 m
1 hm = 100 m
2 km = 2 ∙ 1 000 m = 2 000 m
5 hm = 5 ∙ 100 m = 500 m
2 km 5 hm 8 m = 2 000 m + 500 m + 8 m = 2 508 m
1 254 rotations cover = 2 508 m
1 revolution covers = 2 508 / 1 254 = 2 m
Circumference = 2 m
To find the circumference of the wheel, we can use the formula:
Circumference = Distance Traveled / Number of Revolutions
First, let's convert the given distance into a single unit.
2 kilometers = 2000 meters
5 hectometers = 500 meters
8 meters
Total distance traveled = 2000 meters + 500 meters + 8 meters = 2508 meters
Now we can substitute the values into the formula:
Circumference = 2508 meters / 1254 revolutions
Dividing 2508 by 1254 gives us:
Circumference = 2 meters
Therefore, the circumference of the wheel is 2 meters.
