What is the equation of a circle centred on the origin with a radius of 5?
x² + y² = 25.
What kind of equation gives a circle on a graph?
x2 + y2 = r2 gives a circle centred on the origin, radius r.
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
Is the circle of radius 1 centered at the origin?
Can be centred anywhere. The circle x^2 + y^2 = z^2 is centred at the origin. X, y & z do not require to be different.
A Circle centered at the origin runs through the point 5 12what is the radius of the circle?
x2 + y2 = r2 describes a circle, radius r, centred on the origin. r is thus sqrt(25 + 144) ie 13 units.

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 equation of a circle whose center is at the origin and whose radius is 10?
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100

x2 + y2 = r2 describes a circle, radius r, centred on the origin. r is thus sqrt(25 + 144) ie 13 units.
What is the equation of a circle at the origin and radius 2.5?
x2 + y2 = 6.25
The equation of a circle centered at the origin is x2 plus y2 16. What is the radius of the circle?
If that equals 16 then the radius is 4
What is the radius for a circle with the equation x2 plus y2 equals 9?
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.
Which equation describes the circle with radius 6 that is centered at the origin?
The equation is: x2+y2 = radius2
This circle is centered at the origin and the length of its radius is 5 What is the equation of the circle?
x2 + y2 = 25
