How do you write an equation in standard form of a circle with a center and radius?

The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2


What does each variable represent in standard form?

There are different standard forms for different things. There is a standard form for scientific notation. There is a standard form for the equation of a line, circle, ellipse, hyperbola and so on.


What is the formula for the center of the circle?

The formula for the center of a circle is given by the coordinates ((h, k)) in the standard equation of a circle, which is ((x - h)^2 + (y - k)^2 = r^2). Here, ((h, k)) represents the center of the circle, and (r) is the radius. If the equation is presented in a different form, you can derive the center by rearranging the equation to match the standard form.

How is the Pythagorean theorem used to develop the equation of a circle in standard form?

The Pythagorean theorem is used to develop the equation of the circle. This is because a triangle can be drawn with the radius and any other adjacent line in the circle.


How do you Writing the Equation of a Circle in Standard Form?

What is the standard form of an equation were the poin 3-6 is on a circle whose orgin is the center?

32+62=45 so the standard form is x2+y2=45


What is the center point in the following equation of the circle?

To identify the center point of a circle from its equation, you typically look for the standard form of the circle's equation, which is ((x - h)^2 + (y - k)^2 = r^2). In this format, ((h, k)) represents the center of the circle, where (h) and (k) are constants. If you provide the specific equation of the circle, I can help you determine the center point.

What is standard form linear equation's?

A standard form of a linear equation would be: ax + by = c


What is the circumference of the circle whose equation is (x-9)2 (y-3)264?

The given equation appears to have a typographical error as it does not represent a standard circle equation. The standard form of a circle's equation is ((x-h)^2 + (y-k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. If you can provide the correct equation, I can help you determine the circumference, which is calculated using the formula (C = 2\pi r).


IS it true or false that the solution set of an equation of a circle is all of the point that lie on the circle?

True. The solution set of an equation of a circle consists of all the points that lie on the circle. This is defined by the standard equation of a circle, which is typically in the form ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. Any point ((x, y)) that satisfies this equation lies on the circle.
