**Find the center of a circle with the equation x2+y2âˆ’4x+2y**

Enter Circle Equation Find the equation of a circle that has a diameter with the endpoints given by the points A(1,1) and B(2,4) Step 1: Find the Midpoint ( h , k ) of AB :... A circle's equation can have either a general or standard form. In its general form, ax2 + by2 + cx + dy + e = 0, the circle's equation is more suitable for further calculations, while in its standard form, (x - h)^2 + (y - k)^2 = r^2, the equation contains easily identifiable graphing points like its center and radius. If you have either the circle's center coordinates and radius length or

## How To Find The Center Of A Circle Equation

### To be more precise, There are two possible centres for your circle, which are both equidistant from the line containing A and B and are equidistant from the perpendicular bisector of A and B.

- Given the equation of a circle, state the center and radius. OR... Work backwards! Given the center and radius, write the equation!
- Find centre of circle with equation of tangent given. Ask Question 0. 1 $(4, 1)$ is a point on one end of the diameter of a circle and the tangent through the other end of the diameter has equation $3x- y=1$. Determine the coordinates of the center of circle. What got me about this question was that it didn't give me the circle center and ask me to find the equation of the tangent but instead
- Example 1 Find the equation of a circle whose center is at (2, - 4) and radius 5. Solution to Example 1 Substitute (h , k ) by (2 , - 4) and r by 5 in the standard equation to obtain
- Basic Equation of a Circle (Center at 0,0) A circle with the equation Is a circle with its center at the origin and a radius of 8. (8 squared is 64). Solving the equation for the radius r . The equation has three variables (x, y and r). If we know any two, then we can find the third. So if we are given a point with known x and y coordinates we can rearrange the equation to solve for r: The
