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 is the standard equation?
There is no such thing as a standard equation. Furthermore, there are standard forms - all different - for the equation of a line, a circle, a plane, a parabola, an ellipse and so on. the question needs to be more specific.

When you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
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 is the standard form of an equation where the poin 3-6 is on a circle whose orgin is the center?

When you make the circle bigger or smaller which number of thte standard equation for a circle centered at the origin changes?
The Radius
What is the equation of the circle standard form?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
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.
Which number in the standard equation for a circle centered at the origin should one increase to make the circle larger?
x2 + y2 = r2, the equation of a circle centered at the origin. If you want to make the circle larger, increase the radius length.
What can be said of an ellipse when the two denominator values in its standard equation are the same-?
it becomes a circle
How do you Writing the Equation of a Circle in Standard Form?
(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
