What else can I help you with?
What is the equation of the circle centred at the origin with a radius of 2?
x2 + y2 = 4.
What is the equation of a circle centred on the origin with a radius of 5?
x² + y² = 25.
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.
What kind of equation gives a circle on a graph?
x2 + y2 = r2 gives a circle centred on the origin, radius r.
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 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
What is the radius of a circle where d is the diameter of the circle?
the radius of a circle is r
Wha is the radius of a circle?
The radius of a circle is half the circle's diameter
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
What is the distance from the centre of a circle to any point on the circle?
It is the radius of the circle.
Which is the best defeniton of the radius and and of a circle?
The radius of a circle is halve the circle's diameter.
