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.

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).


When you make the circle smaller which number in the standard equation for a circle centered at the origin decreases?

The radius of the circle decreases when you make the circle smaller.


What are the coordinates of the center of the circle described by the equation x2 y 52 16?

The equation provided appears to have a typographical error, as it should likely be in the form of a standard circle equation. If you meant (x^2 + y^2 = 16), the center of the circle is at the coordinates (0, 0). If this is not the correct interpretation, please clarify the equation for an accurate response.
