a circle
A curved surface on which all points are the same distance from the center is called a sphere.
===> "circle", with center at the "single point" and radius of the "certain distance".
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.

Surface of a sphere
It is a sphere.
The measure of change in elevation in a certain distance is called slope. It is typically expressed as the ratio of the change in vertical height to the horizontal distance between two points on a surface.
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.
That shape is called a circle.
That's called the center
a sphere
They are called equidistant points and form points on a sphere for a solid or a circle on a plane figure.
