The circumference.
Surface of a sphere
the total distance around the rectangle called is perimeter
It is the diameter of the circle or the sphere
The distance around a polygon is the length of its perimeter.
The distance around a circle is its circumference
Diameter is distance across a circle or sphere, circumference is the distance around a circle or sphere
A sphere is the set of all points that have the same distance from one specific point, called the "center".
Sphere.
That is called a sphere.
Surface of a sphere
It is a sphere.
The volume surrounding a magnet will be filled with the lines of magnetic force. Since these are similarly polarized, they repel each other - eventually creating a sphere at a sufficiently large distance. This sphere is the magnetic field of that magnet.
No. The circumference is the distance around a circle or equaltor wheras the radius is the distance from the centre of a sphere (the centre of the earch if you will) to the surface. the diameter is twice the distance of the radius and is the distance from the surface of a sphere, through the middle point across to the other surface.
The sphere far outside the Solar System is called the "Oort Cloud", after the astronomer who predicted its existence.

The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
