Radius: The length from the midpoint of the circle to the outer edge of the circle. The radius is represented by the lowercase letter r.

The formula for the radius can be written as:

r = d/2     or     r = 1/2 d

Diameter: The full length of the circle running from the edge, through the midpoint, all the way to the other side. That is this whole length right here. The diameter of a circle is represented by the letter d.

The formula for diameter can be written as:

d = 2 r

In your own words, describe the relationship that is presented between the radius and diameter of a circle in the comment section.
