Understanding the Relationship Between Radius and Diameter in Geometry

Learn the simple rule: diameter is twice the radius in geometry. Discover how to calculate each with ease.

80 views

The rule for radius and diameter is simple: the diameter is always twice the length of the radius. Mathematically, this is expressed as D = 2R, where D represents the diameter and R represents the radius. To find the radius from the diameter, you can reverse the formula: R = D / 2. This relationship is crucial in various mathematical and practical applications, making it easy to convert between the two measurements.
