a. r = d/2
The equation that represents the relation between the radius r and the diameter d is r = d/2.
Explanation:
- We know that diameter is the largest chord of a circle. It passes through the center of the circle.
- Radius is the distance of the circumference from the center.
- Thus we can say that radius is half the length of diameter. That is, radius = diameter / 2.
