sounds like a sphere to me.
A solid sphere perhaps?
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
A set of points in a plan that are equally distanced from a fixed point is called a circle. equation of a circle is: (x - h)2 + (y - k)2 = r2 Center = (h, k) Radius = r Since Radius (can vary for different circles on that plan) is at equal distance throughout the plan we can therefore say that a set of points in a plan that are equally distanced from a fixed point is called a circle.
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.
Sphere
sounds like a sphere to me.
The radius is always at a fixed, unchanging distance from the center of a circle to all the surrounding points.
A solid sphere perhaps?
The center of the circle. That's how the circle is defined. (The collection of all points on a plane equidistant from a fixed point. The fixed point is the center and the fixed distance is the radius.)
This set of points forms a circle with the fixed point as its center.
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
The set of all points a given distance from a center point is a circle. The given distance is the radius, and the given point is the center. In 3 dimensional space, the set would be the surface of a sphere.
That set of points forms what is known as a "circle".
Its name shall be called "circle".
The distance between the focal point and the center of a circle is called the radius. It is a fixed distance that remains constant for a given circle.
The distance from the fixed point at the center of a circle to any point on the curve is called the radius.
