I hope one of the "following" was:
A circle.
If not, re-submit with the "following" included and I'll see what was really required as an answer.
A curved surface on which all points are the same distance from the center is called a sphere.
It is a sphere.
the center of the circleThat point is called the "center" of the circle.
The set of all points in a plane that are the same distance from a given point, called the center, is known as a circle. The distance from the center to any point on the circle is called the radius. Mathematically, a circle can be defined by the equation ( (x - h)^2 + (y - k)^2 = r^2 ), where ((h, k)) is the center and (r) is the radius.
That shape is called a circle.
This is the center of the circle. From the center of the circle, all the points on the circle are equally distant.
A curved surface on which all points are the same distance from the center is called a sphere.
EquidistantIt's called the center or origin of the circle. All points on a circle are equidistant from the center
Surface of a sphere
It is a sphere.
Because the center of the fan is attacked to something, and if the fan is relatively rigid, other points on the fan keep the same distance from that center. The set of points in a plane that has the same distance from the center is called a circle.
the center of the circleThat point is called the "center" of the circle.
The distance from the center of a lens to one of its focal points is the focal length of the lens.
