How do you graph a circle with center point and radius?

Graphing a circle anywhere on the coordinate plane is pretty easy when its equation appears in center-radius form. All you do is plot the center of the circle at (h, k), and then count out from the center r units in the four directions (up, down, left, right). Then, connect those four points with a nice, round circle.

What is the standard form of a circle calculator?

The standard form of a circle is x2 plus y2 equals the radius squared r2 .

What is the center of the circle x² y² 4x 6y 36 0?

Now we will compare the equation withe the standard form of a circle. Then we conclude that: The center of the circle is: ( 2, -3) and the radius is 7. We can write x^2 + y^2 – 4x + 6y – 36 = 0 in the form ( x- a)^2 + (y-b)^2 = r^2, where the center of the circle is (a,b) and the radius is r.

How do you find the equation of a circle given the center and circumference?

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

How to use the calculator to find center and radius?

Please follow the steps below on how to use the calculator: 1 Enter the center and radius of the circle in the given input boxes. 2 Click on the “Compute” button to compute the graph for the given center and radius of the circle. 3 Click on the “Reset” button to clear the fields and enter the new values.

How do you find the general form of a circle equation?

Step 1: The equation of a circle with center at (h,k) and a radius of r is: In this example h = −3, k = 9 and r = 7, so after substituting into above formula we have: Step 2: Now we will find general form. To find general form we will expand the standard form and bring all terms to the left side.

How do you find the square root of a circle?

Find the center and radius of the circle having the equation: ( x + – ) 2 + ( y + – ) 2 = x 2 + y 2 + – x + – y + – = 0 NOTE: To input square root symbol type letter ‘r’. For example: r13 = 1 3 ​ , 2r3 = 2 3 ​ , 2r (3/5) = 2 5 3 ​ ​ .
