Radius OA, OB, and OE PQ Diameter and chord Example 3: If a circle has a radius of3 cm, what is the length ofits longest chord? Solution: The longest chord is the diameter of the circle. Diameter = 2 × radius = 2 × 3 = 6 cm ...
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
Radius of a circle is the distance between center of circle and the point on circle. Radius is half of diameter, the longest chord of circle. Circumference is the distance around the circle. Radius formula and equation at BYJU’S.
