Apr 3, 2020 · To write the equation of Circle J, you need to know the center coordinates and the length of the radius. You already know that the center is at the origin, which is (0,0) so h=0 and k=0. And you also know that the diameter is 18, and since a radius equals one half of the diameter, r = 18/2 = 9, so the radius is 9.
May 30, 2024 · The standard equation of a circle is given by: \left (x-a\right)^2 + (y-b)^2 = r^2 (x − a)2 + (y − b)2 = r2. where: r r - The radius of the circle. We can use this equation to find the standard form from its center and radius or vice versa.
Dec 21, 2021 · The equation x2 + y2 + 6 x – 4 y – 3 = 0, for example, is the equation of a circle. You can change this equation to the standard form by completing the square for each of the variables. Just follow these steps: Change the order of the terms so that the x 's and y 's are grouped together and the constant appears on the other side of the ...

What is the standard form equaton of a circle? Answer: is a way to express the definition of a circle on the coordinate plane. The formula is $$(x -h)^2 + (y - k)^2 =r^2 $$. h and k are the x and y coordinates of the center of the circle $$(x-9)^2 + (y-6)^2 =100 $$ is a circle centered at (9, 6) with a radius of 10

Jun 27, 2024 · 2 units. To calculate it: Group terms with the same variable and move the constant to the right side of the equation: (x² + 8x) + (y² − 6y) = -21. Complete the square for x and y. Add the same constant to each side: (x² + 8x + 16) + (y² − 6y + 9) = -21 + 16 + 9. Rewrite as the standard form of a circle:
