A sphere.
A curved surface on which all points are the same distance from the center is called a sphere.
It is called the radius. The full distance is called the diameter.
That's a sphere.

The Radius
A curved surface on which all points are the same distance from the center is called a sphere.
Surface of a sphere
The distance from the surface of the Earth to the center is approximately 6,371 kilometers.
The distance from surface to surface through the center of a planet would be that planet's "diameter".
The distance between the surface at the center of a reflective surface and its focal point is equal to half the radius of curvature of the surface.
7,000 km
It is called the radius. The full distance is called the diameter.
That is called a sphere.
The distance from the Earth's surface to its center is approximately 3,963 miles.
A great circle is any circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere is a part of the great circle that passes through them.
A sphere is a shape where the distance from the center to the edge is the same in all directions. This distance is called the radius ( r ). The formula for determining surface volume is Surface area = 4_r2 Volume = 4/3_r3.
The distance from the center of a mirror to the focal point is called the focal length.
