This tool helps you convert the circumference of a circle to its radius quickly and easily.
How to Use the Circumference to Radius Calculator
To use this calculator, simply input the circumference of a circle in the designated text box and click on the “Calculate” button. The calculator will then automatically compute the radius and display the results in a table format.
Calculation Method
The formula used to calculate the radius from the circumference is:
radius = circumference / (2 * π)
Where π (Pi) is approximately 3.14159. The radius is derived by dividing the circumference by the value of 2 times Pi.
Limitations
Please note that this calculator only accepts numerical inputs. Non-numeric values or negative values will result in an error message. Additionally, the precision of the input circumference and the displayed radius is rounded to two decimal places for simplicity.
Use Cases for This Calculator
Designing Circular Fabric Patterns
When you are creating circular fabric patterns for clothing or upholstery, accurately calculating the radius from a given circumference is crucial. This ensures that your designs fit perfectly and use the right amount of material, saving costs and avoiding waste.
Understanding Wheel Sizes
If you are a bicycle enthusiast or a mechanic, knowing the radius of a tire from its circumference helps you understand the size and performance characteristics of a bike. This allows you to make informed decisions when purchasing new tires or adjusting your bike for optimal performance.
