Formula Used in “Standard Form to General Form of a Circle Calculator”
The standard form of a circle equation is expressed as:
x² + y² + Dx + Ey + F = 0
To convert the standard form of a circle into its general form, we can use the following relationship:
(x – h)² + (y – k)² = r²
Where:
- (h, k) = the coordinates of the center of the circle
- r = radius of the circle
Step-by-Step Breakdown of the Formula
To transform the standard form to the general form of a circle, follow these steps:
- Identify the values of h, k, and r.
- Substitute h, k, and r into the general formula.
- Expand the squared terms and combine like terms to achieve the general form representation.
- Reorganize the equation such that all terms are on one side, equating it to zero.
Example Calculation
Let us consider the standard form of a circle: (x – 3)² + (y + 2)² = 16
In this example:
- h = 3
- k = -2
- r = 4 (since r² = 16)
Now, we will substitute these values into the standard equation:
| Step | Calculation | Result |
|---|---|---|
| 1 | Expand (x – 3)² | x² – 6x + 9 |
| 2 | Expand (y + 2)² | y² + 4y + 4 |
| 3 | Combine all terms | x² – 6x + y² + 4y + 9 + 4 – 16 = 0 |
| 4 | Rearrange the equation | x² + y² – 6x + 4y – 3 = 0 |
Thus, the general form of the circle is:
x² + y² – 6x + 4y – 3 = 0
