# Circle Graphing Calculator

A **circle** is a figure obtained by joining all the points in a plane such that every point is at an equal distance from the point at the center.

## What is Circle Graphing Calculator?

'Circle Graphing Calculator' is an online tool that helps to compute the graph for the given center and radius of the circle. Online Circle Graphing Calculator helps you to compute the graph for the given center and radius of the circle in a few seconds.

## How to Use Circle Graphing Calculator?

Please follow the steps below on how to use the calculator:

**Step 1:**Enter the center and radius of the circle in the given input boxes.**Step 2:**Click on the**"Compute"**button to compute the graph for the given center and radius of the circle.**Step 3:**Click on the**"Reset"**button to clear the fields and enter the new values.

## How to Find Graph of the Circle?

Let (x_{1}, y_{1}) be the center of the circle with radius r. (x, y) be an arbitrary point on the circumference of the circle. The standard formula of the circle is given by

**Standard form of the circle is (x - x _{1})^{2} + (y - y_{1})^{2} = r^{2}**

Let us see an example to understand briefly.

**Solved Example:**

Compute the graph of a circle with center (-2, 3) and radius is 5 units.

**Solution:**

Given: Center = (-2,3) and radius = 5 units

Standard form of the circle is (x - x_{1})^{2} + (y - y_{1})^{2} = r^{2}

⇒ (x -(-2))^{2} + (y - 3)^{2} = 5^{2}

⇒ (x + 2)^{2} + (y - 3)^{2} = 25

Similarly, you can try the calculator to compute the graph of the circle for:

- Center = (-4, 5) and radius = 6
- Center = (7, -3) and radius = 9
