1. Spherical, spherical concept
- Spherical concept
In three-dimensional space, when you rotate a half circle with center O, radius R one circle around the axis, also known as diameter AB, will form a sphere.
Rotate the half circle around diameter AB to form a sphere
- Spherical concept
In three-dimensional space, the sphere is a collection of points equidistant from a fixed point O given a constant distance R.
Where, O is the center of the sphere and the distance R is the radius.
