According to Wikipedia,
"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
Area of a circle is pi x r2 Area of a circle having a a radius of 12 units = 3.1416 x 144 units2 = 452.389 units2
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

Divide the circumference by Pi (3.14159), and that will give you the diameter. Divide that number by 2 to find the radius.
If you mean "what is the radius of a circle", then the answer is the line segment or length from the center of circle to the set of points that form the circle. The radius is also half of the diameter.
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.

The radius of curvature is given by(1)where is the curvature. At a given point on a curve, is the radius of the osculating circle. The symbol is sometimes used instead of to denote the radius of curvature (e.g., Lawrence 1972, p. 4).Let and be given parametrically by(2) (3)then(4)where and . Similarly, if the curve is written in the form , then the radius of curvature is given by
In mathematics, the radius of an arc is a straight line from the centre of curvature of the arc to the arc. In the case of a circle it is the line from the circle's centre to its circumference.
This means the vented of a circle. It is the radius of the circle that is perpendicular to a line tangent to any point on the concave side of a smooth curve.
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
radius of curvature = 2Focal length
The radius of curvature is the distance from the center of a curved surface or lens to a point on the surface, while the center of curvature is the point at the center of the sphere of which the curved surface is a part. In other words, the radius of curvature is the length of the line segment from the center to the surface, while the center of curvature is the actual point.
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
The question, as stated, does not make sense.The radius (not raduis) of curvature of a curve at a point is the radius of the arc of a circle which approximates the curve in the immediate vicinity of the point.
The radius of curvature of a lens is the distance between the center of the lens and its focal point. It is a measure of the curvature of the lens surface. A smaller radius of curvature indicates a more curved lens, while a larger radius indicates a flatter lens.
