352 views

To find the radius from the diameter, divide the diameter by 2. For example, if the diameter is 10 units, the radius would be 10 / 2 = 5 units. This simple formula applies to circles in any context, making calculations straightforward and easy.

FAQs & Answers

  1. What is the difference between diameter and radius? The diameter is the distance across a circle through its center, while the radius is half of the diameter, extending from the center to the edge.
  2. How do I calculate the area of a circle using the radius? To calculate the area of a circle, use the formula A = π * radius², where A represents the area.
  3. What are the practical applications of radius and diameter? Radius and diameter are used in various fields such as engineering, architecture, and even everyday object measurements.
