Understanding the Circle Measurements
To use the calculator effectively, it helps to understand the measurements involved.
Circumference
Circumference is the total distance around a circle.
Diameter
The diameter is a straight line passing through the center of the circle, connecting two opposite points on its edge.
Radius
The radius is the distance from the center of the circle to its edge.
Area
Area measures the amount of space inside the circle.
These measurements are mathematically connected, which allows the calculator to determine all values from a single circumference input.
