A circle is all of the points that are equal distance from the center of the circle to the edge of the circle. This distance is called the radius of the circle. All points are the same distance from the center. The radius is half of the diameter. r = d/2.
•find the centre and radius of a circle, given its equation in standard form; •find the equation of the tangent to a circle through a given point on its circumference; •decide whether a given line is tangent to a given circle.
Learn the relationship between the radius, diameter, and circumference of a circle.
Radius-A segment from the center of the circle to a point on the circle(the distance from the center to a point on the circle.) Circumference – distance around the edge of the circle Congruent Circles-two circles with the same radius. Diameter – A segment that goes through the center of the circle, with both endpoints on the edge of the circle.

Radius: a line segment drawn from the center of a circle to one of the points on the circle. Chord: a line segment connecting two points on a circle. Diameter: a chord that passes through the center of a circle. Tangent: a line that has exactly one point of intersection with a circle. Point of Tangency: Arc:
What Is the Radius of a Circle? The radius of a circle represents the distance between the center and the boundary of the circle (circumference). The radius is generally denoted by “R” or “r.” The word “radius” is the singular form, while “radii” is the plural form.
