The diameter of wheel is 28 cms .how many revolutions will it make in moving 1100 m
(1100*100)/(14pi) = 2501
oops. double that. I took c=pi*r, not pi*d.
Double the 14, not the answer:
(1100*100)/(28pi) = 1250.5
To find out the number of revolutions the wheel will make in moving 1100 meters, we need to use the formula:
Number of revolutions = Distance / Circumference
Let's start by calculating the circumference of the wheel.
The formula for the circumference of a wheel is:
Circumference = π * Diameter
Given that the diameter of the wheel is 28 cm, we can substitute this value into the formula:
Circumference = π * 28 cm
Now, we need to calculate the value of π (pi). Pi is a mathematical constant approximately equal to 3.14159.
Circumference = 3.14159 * 28 cm
Now we can calculate the circumference:
Circumference ≈ 87.964 cm (rounded to three decimal places)
Next, we can calculate the number of revolutions:
Number of revolutions = 1100 m / 87.964 cm
Since the distance is given in meters and we have the circumference in centimeters, we need to convert the distance to centimeters.
1 meter = 100 centimeters
1100 m = 1100 * 100 cm = 110,000 cm
Now we can calculate the number of revolutions:
Number of revolutions = 110,000 cm / 87.964 cm
Number of revolutions ≈ 1,250.028
Therefore, the wheel will make approximately 1,250 revolutions in moving 1100 meters.
