Conclusion

π (pi) is a constant value

This is not true. The circumference is always longer than the diameter, and the difference increases as the circle's radius increases.

To find the radius, rearrange the formula: r = Circumference / (2π)

What if I want to find the radius of a circle if I know its circumference?

While π is approximately 3.14, it is an irrational number and its value can be calculated to an arbitrary number of decimal places.

Common misconceptions

The circumference of a circle is always equal to its diameter

The circumference formula shows that the circumference of a circle is directly proportional to its radius. As the radius increases, the circumference also increases.

To calculate the circumference, simply plug the radius into the formula: Circumference = 2πr
