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.
What is the centre and radius of a circle passing through the points of 6 3 and -5 2 and 7 2 on the Cartesian plane?
Points: (6, 3) (-5, 2) and (7, 2) Circle's equation works out as: (x-1)^2+(y+3)^2 = 61 Centre of the circle is at: (1, -3) Radius of the circle is the square root of 61 which is about 7.81 to two decimal places
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.
What is the centre and radius of a circle enscribed through the points of 6 2 and 8 -2 and 0 2 on the Cartesian plane?

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 Cartesian equation of a circle whose centre is in the 1st quadrant with a radius of 7 and touches the x and y axes?
Centre of the circle is at (7, 7) and its Cartesian equation is (x-7)^2 + (y-7)^2 = 49
What is the centre and radius of a circle passing through the points of 6 3 and -5 2 and 7 2 on the Cartesian plane?
Points: (6, 3) (-5, 2) and (7, 2) Circle's equation works out as: (x-1)^2+(y+3)^2 = 61 Centre of the circle is at: (1, -3) Radius of the circle is the square root of 61 which is about 7.81 to two decimal places
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.
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.
What is the centre and area in cm of a circle whose circumference cuts through the points of 1 0 and 7 -6 and 7 0 on the Cartesian plane?
It works out that the centre of the circle is at (4, -3) on the Cartesian plane and its area is 56.549 square cm rounded up to three decimal places.
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.
