o no flat surface.
Of the infinitely many points on a sphere, no two are the same as each other.
Only one - its centre.
The surface of a sphere. It cannot be a sphere since points which are not on its surface will be nearer to the centre.
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
any two points on the sphere ;)
None. A marble is a sphere, so there are no points where lines intersect.
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
A2. A globe is a simple sphere, and has no connection points. A soap bubble is among the simplest.We may draw imaginary lines around the sphere, and make other markings, but these are marks on a sphere, not the sphere itself.
Yes, it is true. In a perfect geometric sphere, all points on its surface are equidistant from its center. This property is one of the defining characteristics of a sphere.
The radius of a circle or a sphere has infinite number of points.
Two points. These may coincide if the line is a tangent to the sphere.
It is the set of all points [from some fixed point] at a distance of 1 unit, where the points on the surface of the sphere are included in the set.
