Radius divided by diameter
WebMar 30, 2024 · The distance from the centre to any point on the circumference is the radius, marked with the letter r. With that in mind, the diameter is created by extending the radius to the opposite side of the sphere (d). However, the diameter must go through the centre, and points connected by diameter are antipodal points of each other.
