Circumference
How do you find radius of a circle?
Draw a line from any part on the outside of a circle to the exact center of the circle. * * * * * That is fine if you know where the center is but not much use if you are just given a circle and do not know where the exact centre is. In this case: Draw a chord - a straight line joining any two points on the circumference of the circle. Then draw the perpendicular bisector of the chord. Draw another chord and its perpendicular bisector. The two perpendicular bisectors will meet at the centre.
Can you draw a circle if you only know the measure of a chord that is not a diameter explain.?
Given only a chord of the circle, you do not have enough information to draw it. You do however have enough information to limit the location of the circle to a single line. You can find a line that the centre of the circle lies on by taking the average of the two points that are given, and the negative reciprocal of the slope to the line that they lie on. With that inverted slope and with the the middle point between the two given ones, you can now define another line that passes through the centre of the circle. This does not however give you a single circle, as the centre point could be anywhere on the line. If you are given a second chord, you could find the centre of the circle by finding two lines on which it lies and getting their point of intersection. Similarly if you are given any measurement that is related to its radius (e.g. area, circumference) you could work it out with that as well.
What name is given to the line traced by a pair of compasses to form circle?
radius Additional answer Actually, the radius is the line that joins the centre to the circumference. The line that compasses draw to trace a circle is just that, a circle.
What is the name that is given to the outside of a circle?
The circumference
How many lines can be drawn through a given point on a circle that is tangent to the circle?
Infinite lines because a circle has infinite lines of symmetry.
More Information about Euclid's third postulate?
The postulate states that given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as centre. I am not sure that there is more information than that!

What is the locus of the centers of circles that are tangent to a given circle O at a given point A on circle O?
Join the centre of the circle O and the point A .Extend it to both sides to form a line.This is the required locus
How do you construct a line tangent through a circle through a point outside the circle?
The tangent line only touches the outside of a circle at one given point. So an outside line perpendicular to the circle's diameter at 90 degrees should do.

How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
What is the radius of 28 cm?
It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.
