The radius of a pulley is 161 mm. Find the circumference of the pulley.

Recall that C = 2πr

3178

The radius of a pulley is 97 mm. Find the circumference of the pulley.

To find the circumference of a pulley, you can use the formula: `Circumference = 2 * π * radius`.

In this case, the given radius of the pulley is 161 mm.

So, to find the circumference, substitute the value of the radius into the formula:

Circumference = 2 * π * 161 mm

Now we need to determine the value of π. π is a mathematical constant approximately equal to 3.14159.

Therefore, the formula could be rewritten as:

Circumference ≈ 2 * 3.14159 * 161 mm

Calculating this expression gives:

Circumference ≈ 1009.86044 mm

Therefore, the circumference of the pulley is approximately 1009.86044 mm.
