To calculate the radius from two points, you need the distance (d) between the points, which acts as the diameter. Use the distance formula `d = √((x2 - x1)² + (y2 - y1)²)`, and then divide by 2 to find the radius: radius = d / 2.

FAQs & Answers

  1. What formula is used to calculate the distance between two points? The distance between two points (x1, y1) and (x2, y2) is calculated using the formula `d = √((x2 - x1)² + (y2 - y1)²)`.
  2. How do I find the radius from the diameter? To find the radius, simply divide the diameter by 2. If the diameter is the distance between two points, then radius = distance / 2.
  3. Can I calculate the radius if I only have one point? No, you need two distinct points to calculate the diameter, which is required to find the radius.
  4. What applications require calculating the radius from two points? Calculating the radius from two points is useful in various fields such as geometry, physics, and engineering, particularly when dealing with circles or circular motion.
