Equation of the circle graphed
WebJul 8, 2024 · Because both h and v are zero, they can disappear and you can simplify the standard circle equation to look like. For instance, to graph the circle. follow these steps: Realize that the circle is centered at the origin (no h and v) and place this point there. Calculate the radius by solving for r. Set r -squared = 16. In this case, you get r = 4. WebJul 9, 2024 · The equation of a circle appears as (x – h) 2 + (y – v) 2 = r 2. This is called the center-radius form (or standard form) because it gives you both pieces of information …
