Radius And Diameter Calculator 

Understanding the relationship between a circle’s radius and diameter is fundamental in geometry, engineering, design, and construction. The Radius And Diameter Calculator helps students, professionals, and hobbyists quickly compute either value when one is known.

This tool eliminates manual calculations, saving time while ensuring accuracy for projects ranging from classroom assignments to real-world engineering applications.

How to Use the Radius And Diameter Calculator

Using the calculator is simple:

1. Enter Known Value: Input either the radius or the diameter of the circle.
2. Click Calculate: The tool automatically computes the missing value.

The formulas used are:

• Diameter to Radius: $r = \frac{d}{2}$r=2d​
• Radius to Diameter: $d = 2 \times r$d=2×r

Where:

• $r$r = radius
• $d$d = diameter

Example Calculations

Example 1: Find the diameter if the radius is 7 cm.

• Diameter = 2 × 7 = 14 cm

Example 2: Find the radius if the diameter is 20 inches.

• Radius = 20 ÷ 2 = 10 inches

With the Radius And Diameter Calculator, these calculations are instantaneous, helping you focus on design or problem-solving.
