What is the radius of a circle?
Dear Student,
A radius is a straight line from the center of a circle to the circumference of a circle. If you have two or more of them, they are referred to as radii. All radii in a circle will be the same length.
Given the diameter of a circle, the radius is simply half the diameter:
radius r = Diameter/2 = D/2
Regards
