How to Use the Radius and Diameter Calculator
Using the Radius and Diameter Calculator is simple and intuitive. Here’s how you can quickly get the results you need:
Step 1: Input the Radius or Diameter
- Enter the radius: If you know the radius of the circle, simply type it into the “Radius (cm)” input field.
- Enter the diameter: If you have the diameter, type it into the “Diameter (cm)” input field.
Step 2: View Results
Once you’ve entered either the radius or diameter, the calculator will automatically compute the missing value. The results are displayed on the screen as follows:
- Radius: The calculated or entered radius of the circle.
- Diameter: The calculated or entered diameter of the circle.
Step 3: Reset the Calculator
If you need to calculate for a different circle, simply click the “Reset” button, and all fields will be cleared.
Example Calculation
Let’s take a look at an example of how the Radius and Diameter Calculator works:
- If you know the radius of a circle:
Suppose the radius is 7 cm.
The calculator will automatically calculate the diameter as 14 cm (since Diameter = Radius × 2). - If you know the diameter of a circle:
Suppose the diameter is 12 cm.
The calculator will automatically calculate the radius as 6 cm (since Radius = Diameter ÷ 2).
By using this tool, you can quickly convert between radius and diameter without any complicated formulas.
