What is the name for a chord that passes through the center of a circle?
The chord that passes through the centre is the biggest chord in a circle and it is the diameter.
All chords of a circle pass through the center of a circle?
Not true because only the largest chord passes through the center of a circle which is its diameter
What is a straight line going across a circle from side to side through the centre?
diameter
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.
True or false the radius r of circle is the distance across the circle through its center?
False:: The distance from the circle centre to the circulference is the RADIUS. However, As a straight line, the distance from the circumference , through the circle centre to to circumference on the opposite side is the Diameter. The diameter is twice the radii. Algebraically, d = 2r.
What is the centre and radius of a circle passing through the points of 5 5 and 8 5 and 5 1 on the Cartesian plane?
Using the formula of x^2 +2gx +y^2 +2fy +c = 0 it works out that the centre of the circle is at (6.5, 3) and its radius is 2.5 units in length. Alternatively plot the points on the Cartesian plane to find the centre and radius of the circle.
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 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.
What is the centre and radius of a circle that passes through the points of 2 0 and 3 1 and -6 10 on the Cartesian plane?
The equation of the circle works out as: (x+2)^2 + (y-5)^2 = 41 The circle's centre is at: (-2, 5) Its radius is the square root of 41
What is the radius of a circle and its centre that passes through the points of 5 0 and 3 4 and -5 0 on the Cartesian plane?
Points: (5, 0) and (3, 4) and (-5, 0) Equation works out as: x^2+y^2 = 25 Radius: 5 units in length Centre of circle is at the point of origin (0, 0) on the Cartesian plane.
What is the center and radius of a circle whose circumference passes through the points 5 0 and 3 4 and -5 0 on the Cartesian plane?
It has centre (0, 0) and radius 5.
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 the centre of a circle called?
The Origin ( or just "origin") * * * * * That is not generally true. The general formula for a circle, in the Cartesian plane, is of the form (x-a)2 + (y-b)2 = r2 where the coordinates of the centre are (a,b) and the radius is r. It is only if both a and b are 0 that the centre is the origin.
What is the distance that passes through the centre of a circle called?
It is the diameter of the circle.
What is a chord that passes through the centre of the circle called?
It is the circle's diameter
What is the center and radius of the circle of x squared plus y squared -4x -6y -3 equals 0 enscribed on the Cartesiian plane?
x2+y2-4x-6y-3 = 0 Using the appropriate formula it works out as:- Centre of circle: (2, 3) Radius of circle: 4.
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
