Circle graphing calculator is an online mathematical tool to represent a circle graphically. Using the standard form of circle equation, we can draw the circle with given radius and center point. Standard circle equation is given below.

$(x-a)^{2}$+$(y-b)^{2}$=$r^{2}$
Where (a,b) is center point
r is the radius of curvature

Default circle center points and radius are given below in the circle standard form equation calculator. Circle is shown graphically according to the default points given. In case of circle general form equation, default center coordinates are plugged in and circle is shown graphically.

## Steps for Circle Graphing Calculator

Step 1 :

Pick out the values of a,b and radius r from the given standard circle equation.

Step 2 :

Represent the circle graphically by using the given center point and radius.

## Problems on Circle Graphing Calculator

1. ### Represent $(x-3)^{2}$+$(y-2)^{2}$=1 graphically.

Step 1 :

From the given equation it is clear that,

Center point (a,b)=(3,2) and radius r=1

Step 2 :

By using the given values the circle can be represented as,

The given circle is,

2. ### Represent $(x+1)^{2}$+$(y-2)^{2}$=4 graphically.

Step 1 :

The center point and radius is given that,

(a,b)=(-1,2); r=2

Step 2 :

By using this values the circle can be drawn as
