No, two radii do not always form a diameter. A diameter is specifically formed when the two radii extend from the center of the circle to opposite points on the circle's boundary, creating a straight line through the circle’s center.

FAQs & Answers

  1. What is the definition of a diameter? A diameter is a straight line segment that passes through the center of a circle, connecting two points on its boundary.
  2. Can a single radius form a diameter? No, a single radius cannot form a diameter; it must connect two opposite points on the circle through the center to qualify as a diameter.
  3. How many diameters can a circle have? A circle can have an infinite number of diameters, as any line segment that passes through the center and connects two points on the circumference qualifies.
  4. What is the relationship between radius and diameter? The diameter is twice the length of the radius; specifically, D = 2r, where D is the diameter and r is the radius.
