What is the equation of the circle passing through the origin and having centre at X-axis?
Indus
(x-a)^2+(y-0)^2=a^2 here the centre lies on x axis thus the centre wud be a point (a,0) and thus as it passes thru origin radius becomes a. as passes thru (0,0) LHS=(0-a)^2+(0-0)^2=a^2 RHS=a^2

What equation represents the graph of a circle?
Equation of a circle when its centre is at (0, 0): x^2 + y^2 = radius^2 Equation of a circle when its centre is at (a, b): (x-a)^2 + (y-b)^2 = radius^2
What is the radius of a circle with the diameter of 6?
The diameter is the length of a straight line, from one side of the circle to the other, passing through the centre. The radius is a straight line from the circle centre to the circle itself and is always = half the length of the diameter, so 6 * 0.5 = 3
What is the equation of a circle with center at 3 -5 passing through the point 6 -7?
Equation of circle: (x-3)^2 +(y+5)^2 = 13
If the radius of a circle is 18 inches what is the diameter?
36 inches. The radius is the distance from the centre to the outside or circumference and trhe diameter is the distance across passing through the centre. Therfore the diameter is twice the distance of the radius.
What is the equation of a circle with center (3 8) and a radius of 2?
Centre of the circle: (3, 8) Radius of the circle: 2 Cartesian equation of the circle: (x-3)^2 + (y-8)^2 = 4
What is a chord passing through the center of a circle?
a diameter
How many lines of symmetry does a circle in circle?
An infinite number, all passing through the centre.
What is a diameter of a circle made up off?
The diameter of a circle is twice its radius and spans the circle passing through its centre.
How do you mark equidistant points on circle?
It is the radius from the centre to the circumference or the diameter passing through the centre to both sides of the circumference
What is the radius of a circle with a 3cm diameter?
The radius would be HALF the diameter, making the answer 1.5cm ! The diameter of a circle is the distance across it, passing through the centre. The radius is the distance from the centre to the edge.
How do you convert diameter into width?
The diameter of a circle is the width of the circle. The measurement in a straight line from edge to opposite edge passing through the centre.
Why are radius and diameter different?
The radius is half of the diameter. The radius of a circle is the distance from the centre to the circumference. The diameter of a circle is the length of a straight line from one point on the circumference to another, passing through the centre of the circle.
Can a chord of a circle also be a diameter of a circle And why?
A chord is a straight line that spans the circumference of a circle and the diameter of a circle is a straight line in a circle spanning its circumference and passing through the circle's centre.
Best describes the diameter of a circle.?
The diameter of a circle is twice its radius or its largest chord passing through the center of the circle.
How do you find the center of a circle with the diameter of 5 meters?
The diameter of a circle is a straight line drawn from edge to edge passing through the centre. Therefore, the centre of the circle is half the diameter: 5/2=2.5 metres.
Is circumference shorter or longer then radius or diameter?
It's longer than both. The circumference - is the distance around the circle... The diameter - is the distance across the circle, passing through the centre... The radius - is the distance from the centre of the circle to the edge.
Why is the radius of the circle half the diameter?
The radius of a circle is the distance from the centre to the rim. The diameter is the distance fron rim to rim passing through the centre point. It therefore follows that the radius is half the diameter
