It is the distance, from any point on a curve, to the centre of curvature at that point.
Twice the radius.
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:]
RADIUS
In math, radius is the distance from the center of a circle to any point on the circle. It is half the diameter of a circle.
The radius bone sounds like a math term because "radius" is also a term used in geometry to refer to the distance from the center of a circle to any point on its circumference.
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.
radius times two
The distance from the center of a circle to its perimeter
you do math
My math teacher said pir2 in other words pi x radius to the second power.
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
