What is the radius and diameter of a circle?

The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.


The circular boundry of the circle is called the?

The boundary which defines the area of a circle is known as the circumference of the circle.However if one wants to be precise, the circumference is the distance around the outside of the circle, not the circle itself. The term "circle" itself means the boundary. It has an interior and an exterior.A circle can be defined as all the points that are the same distance from a given point.

Is there only two radius's in a circle?

Technically there are an infinite number of radii in a circle. A radius is a line from the center of the circle to a point on its edge, and since there are an infinite number of points on a circle's edge there are an infinite number of radii.

What name is given to the line that traces the edge of a circle?

The curved line that traces the boundary or perimeter of a circle is called the circumference. A straight line that touches the circle at just one point is called a tangent. See the related link, 'The Parts of the Circle', below this answer.
