The diameter is a straight line segment that passes through the center of a circle or sphere, connecting two points on its boundary. It is the longest distance across the figure and is twice the length of the radius, which is the distance from the center to the edge. In mathematical terms, for a circle, the diameter can be calculated as twice the radius (D = 2r). The diameter is a key measurement in understanding the size and proportions of circular shapes.

Why did they need pi?

The term used is pi
What are the dimensions of circle?
The three most common ways to describe the dimension or size of a circle is either the diameter or the radius or the circumference (perimeter).When the circumference is given then dividing that by Pi will give you the diameter (circumference / Pi = diameter).

What is the diameter of a 6 foot table?
If you describe a table as being 6 foot, that would normally mean that it is 6 feet long, and rectangular in shape rather than round. Only round tables have a diameter. The term doesn't apply to rectuangular tables.
