Diameter of a Sphere

Short Definition

(This is 10th grade math, please don't make it advanced)

The diameter of a sphere is the distance across the sphere passing through its center, and it is twice the length of the sphere's radius.

The diameter of a sphere is the distance between any two points on the sphere that pass through the center. It can also be defined as twice the length of the radius of the sphere. In simpler terms, it is a straight line passing through the center of the sphere, and its length can help describe the size of the sphere.
