The radius of a pulley is 164 mm. Find the circumference of the pulley.
2πr
Why did the pulley bring a tape measure to the party? Because it wanted to show off its circumference, of course! Ha, ha! But seriously, to find the circumference of a circle, we use the formula C = 2πr, where r is the radius. So, let's plug in the radius of 164 mm into the formula. Taking π as approximately 3.14, we get: C = 2 * 3.14 * 164 mm. Solving this multiplication, we find that the circumference of the pulley is approximately 1,028.48 mm.
To find the circumference of a pulley, you can use the formula:
Circumference = 2 * π * radius
Given that the radius of the pulley is 164 mm, let's plug this value into the formula:
Circumference = 2 * π * 164 mm
Now, we can calculate the circumference. The value of π (pi) is approximately 3.14159. Let's substitute this value into the formula:
Circumference ≈ 2 * 3.14159 * 164 mm
Calculating the expression within the brackets:
Circumference ≈ 6.28318 * 164 mm
Multiplying:
Circumference ≈ 1028.51 mm
Therefore, the approximate circumference of the pulley is 1028.51 mm.
To find the circumference of a circle (in this case, the pulley), you can use the formula:
Circumference = 2 * π * Radius
Given that the radius of the pulley is 164 mm, we can substitute this value into the formula to find the circumference.
Circumference = 2 * π * 164 mm
The value of π (pi) is a mathematical constant that is approximately equal to 3.14159. When we multiply it by 2 and the radius, we get:
Circumference ≈ 2 * 3.14159 * 164 mm
Calculating this, we find:
Circumference ≈ 1029.39496 mm
Therefore, the approximate circumference of the pulley is 1029.39496 mm.
