What is the Radius of Circle?
Radius is a line segment that connects the center of a circle or sphere to its boundaries. The plural of radius is “radii”.
The diameter of a circle or sphere is the longest line segment connecting all points on the opposite sides of the centre, while the radius is half the length of the diameter.
Radius of a Circle Definition
The radius of a circle is the distance from the center of the circle to any point on its circumference. It is a constant length for a given circle and is half the diameter of the circle. The radius is typically denoted by the symbol r.
Radius of Circle
Radius of Circle: The radius of a circle is the distance from the circle’s center to any point on its circumference. It is commonly represented by ‘R’ or ‘r’. The radius is crucial in nearly all circle-related formulas, as the area and circumference of a circle are also calculated using the radius.
