1. What is Diameter of Circle of Cardioid?

The Diameter of Circle of Cardioid is a straight line passing from side to side through the center of the circle of Cardioid. It represents the longest distance across the circle and is twice the length of the radius.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( D \) — Diameter of Circle of Cardioid (m)
• \( r \) — Radius of Circle of Cardioid (m)

Explanation: The diameter is simply twice the radius of the circle, which is a fundamental relationship in circle geometry.

3. Importance of Diameter Calculation

Details: Calculating the diameter is essential for understanding the size and scale of the cardioid's generating circle, which is crucial in various geometric and engineering applications involving cardioid shapes.

4. Using the Calculator

Tips: Enter the radius value in meters. The value must be positive and valid (radius > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between diameter and radius?
A: The diameter is always exactly twice the length of the radius in any circle.

Q2: Can this formula be used for any circle?
A: Yes, the relationship D = 2r holds true for all circles, including the circle of cardioid.

Q3: What units should I use for the radius?
A: You can use any consistent unit of length (meters, centimeters, inches, etc.), but the calculator defaults to meters.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact, assuming the radius measurement is accurate.

Q5: What if I have the circumference instead of the radius?
A: You can calculate the diameter using D = C/π, where C is the circumference.
