Find the distance between the point (-3, -4) and the origin to find the radius of the circle.
This is the distance formula:
d = ( ((x2 - x1)^2) + ((y2 - y1)^2) ) ^ 0.5
These are the points:
(x1, y1) = (0, 0)
(x2, y2) = (-3, -4)
d = ( ((-3 - 0)^2) + (-4 - 0)^2) ) ^ 0.5
d = ( (-3^2) + (-4^2) ) ^ 0.5
d = ( 9 + 16 ) ^ 0.5
d = ( 25 ) ^ 0.5
d = 5
Now that you know the radius of the circle, to find the diameter, just double it.
5 * 2 = 10
The diameter of the circle equals 10.
The straight-line measurement from one point to another through the origin of a circle is the diameter of the circle.
True, the definition of incenter is the point forming the origin of a circle within a triangle.Hopefully this helps :)
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.

No. The only chords that go through the center is a diameter.
origin
The distance between two sides of a circle that are parellel, the diameter line must pass through the origin
The unit circle is a circle with its center at the origin and a radius of ' 1 '.
The straight-line measurement from one point to another through the origin of a circle is the diameter of the circle.
The center of a circle is called the origin. It is a point at one end of a radius, the other end of which defines the circumference of the circle.
EquidistantIt's called the center or origin of the circle. All points on a circle are equidistant from the center
A ray is defined as having an origin but no endpoint (unless you count the origin as an endpoint, in which case it has 1).
Center (origin) Circumference
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 = 64
x² + y² = 81.
