# The circumference of a circle is always a mystery!

## Introduction

Introduction: You go to a science museum and see a exhibit on the circumference of a circle. The exhibit is about circles and how they vary in size. You ask the museum attendant what the circumference of a circle is and he tells you it’s always a mystery! Have you ever wondered what that means? This question is at the heart ofcircle analysis, or how to measure the size of a circle.

## What is the circumference of a circle.

The circumference of a circle is the circumference of the circumscribing circle. This means that the diameter of a circle is equal to its circumference. The radius of a circle is also equal to its circumference, so the circumference of a circle is always equal to r.

## What is the circumference of a circle with a given diameter.

The circumference of a circle is the length of its edge divided by its diameter. For a circle with a given area, the circumference is the sum of all the circles within that area.

## What is the circumference of a circle with a given radius.

The circumference of a circle is the length of its circumference or perimeter. The circumference of a circle with a given radius is simply the square of its radius.What is the circumference of a circle with a given areaWhat is the circumference of a circle with a given areaThe circumference of a circle is the length of its area (or diameter). The circumference of a circle with a given area is simply the sum of its lengths, divided by its diameter.

## Conclusion

The circumference of a circle is the distance between its two ends.
