Circle Calculator

Use the format \( x^2 + y^2 = r^2 \) for standard form equations.

What is a Circle Calculator?

The Circle Calculator is a simple yet powerful tool that helps you calculate essential properties of a circle based on its equation in standard form. By inputting a circle equation, such as \( x^2 + y^2 = r^2 \), the calculator provides detailed results for the circle's center, radius, diameter, circumference, area, x- and y-intercepts, domain, and range. Additionally, it generates a graphical representation of the circle for better visualization.

How Does the Circle Calculator Work?

The Circle Calculator is designed to be user-friendly and efficient. Here's how you can use it:

  1. Input the Circle Equation: Enter the equation of the circle in the standard form \( x^2 + y^2 = r^2 \). For example, \( x^2 + y^2 = 9 \).
  2. Click the Calculate Button: Press the "Calculate" button to generate the results.
  3. View the Results: The calculator will display the circle's properties step by step, along with a graph showing its shape.
  4. Clear the Input: Use the "Clear" button to reset the calculator and input a new equation.
