To find the circumference of a pulley, you can use the formula:
Circumference = 2 * π * radius
Given that the radius of the pulley is 140mm, you can substitute this value into the formula:
Circumference = 2 * π * 140mm
Now, we can calculate the circumference:
Circumference ≈ 2 * 3.14159 * 140mm
Circumference ≈ 879.646mm
Therefore, the circumference of the pulley is approximately 879.646mm.
To find the circumference of a pulley, you can use the formula:
Circumference = 2 * π * radius
Given that the radius of the pulley is 140mm, we can substitute this value into the formula:
Circumference = 2 * π * 140mm
First, let's convert the radius into the appropriate units. Since the radius is given in millimeters (mm), let's convert it to meters:
Radius = 140mm = 140 / 1000 = 0.14 meters
Now we can calculate the circumference using the formula:
Circumference = 2 * π * 0.14 meters
The value of π (pi) is a mathematical constant approximately equal to 3.14159. So, we can substitute this value into the equation:
Circumference = 2 * 3.14159 * 0.14 meters
Calculating this expression will give us the circumference of the pulley in meters.
