# How to Use a Circle to Find the Length of s

## What You’ll Need

To find the length of s using a circle, you’ll need a circle and a calculator. You’ll also need to know the radius of the circle.

## Formula for Finding the Length of s

The formula for finding the length of s is s = 2πr, where r is the radius of the circle. This formula can be used to calculate the length of s in any circle.

## Steps to Finding the Length of s

Once you have your circle and the radius of the circle, you can use the following steps to find the length of s:

1. Calculate the circumference of the circle (C = 2πr).

2. Divide the circumference by the radius of the circle to calculate the length of s (s = C / r).

3. Enter the formula into your calculator and press enter to calculate the length of s.

## Conclusion

By following the steps above, you can easily find the length of s using a circle. All you need is a circle and a calculator, as well as the radius of the circle. Once you have those, you can use the formula s = 2πr to calculate the length of s.
