Answer: radius
Step-by-step explanation:
We know that the distance from the center of a circle to the point present on circle is known as radius of the circle.
Therefore, A point is on a circle , if the distance from the center of the circle to the point is equal to the radius.
Whereas, the distance of a point from another point on a circle passing from circle of the circle is known as diameter of the circle.
The circumference of a circle is the distance around the circle.
