Learn about the circle distance formula and how it calculates the distance between two points on a circle's circumference.

198 views

The circle distance formula, also known as the chord length formula, is: D = 2 r sin(θ/2) where D is the distance between two points on the circle, r is the radius of the circle, and θ is the central angle between the two points in radians. This formula helps in finding the straight-line distance between two points on the circumference of a circle.

FAQs & Answers

  1. What is the chord length formula? The chord length formula is D = 2r sin(θ/2), where D is the distance, r is the radius, and θ is the angle in radians.
  2. How do you calculate the distance between two points on a circle? You can calculate the distance using the circle distance formula, which accounts for the radius and the angle between the points.
  3. What is the significance of using radians in the formula? Radians are the standard unit of angular measurement used in mathematics, providing a direct relationship between arc length and radius.
