Non-examples of radius in math include concepts such as diameter, which measures the distance across a circle through its center, and circumference, the total distance around the circle. Additionally, a line segment that does not connect the center to the edge of the circle, such as a chord that does not pass through the center, is not a radius. Other non-examples include any measurements related to polygons or other shapes that do not involve a circle.
I have no idea I suck at math < B
It refers to the radius of a circle which is half of its diameter.
radius is half of a circle. when u make a line from the middle of the circle to the edge would be the radius:]
When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
