radius
"Radius" is a measurement that refers to a circle. It's the distance from the circle's center to any point on its curve.
A circle.
That refers to the center of the circle that "fits best" - that follows the direction of a curve (locally) most closely. (The formal definition, of course, is a bit more complicated, and involves concepts of calculus, such as limits.)
no. its the inside Diameter is the measurement from one side of the circle, through the center, to the opposite side. Circumference is the measurement around the circle.

A circle.
The easiest way to find the radius (measurement from the outside to the center of a circle) is to measure the diameter and divide by 2.
"Diameter" is the distance all the way across the circle, through the center."Radius" is 1/2 of the diameter ... the distance from the center to the curvy part of the circle."Circumference" is the distance all the way aroundthe circle.
This is the center, or locus, of a set of points, such as a curve or circle.
A plane curve all equidistant from a given fixed point, the center.
It is its square area which is found by pi*radius squared
