With a compass
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
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.
The radius is the distance from the center of the circle to its edge. No matter how you draw this radius, it is one value of one length only, for any given circle.

Radii are always positive. No, it is not possible to draw a circle with negative radius.
With a compass
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.

The area of a circle is: pi times radius squared
The default method for drawing a circle is to specify a center point and radius.You can draw circles using any of the following methods:Center-RadiusCenter-DiameterTwo pointsThree pointsRadius-Tangent-TangentConvert Arc to CircleTo draw a circle by specifying its center and radiusDo one of the following:Choose Draw> Circle>center, radiusOn the Draw 2D toolbar, click the Circle Center-Radius tool.Type circle and then press Enter.Specify the center point.Specify the radius of the circle.

If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
