We will discuss about constructing a circle when radius is known. Consider the following example.

Step 1 : Measure the compass for 4 cm on a scale.
Step 2 : Mark a point in the sheet and name it O to be the center of the circle.
Step 3 : Place the pointer of the compass on O.
Step 4 : Complete the circle by turning the compass with the pointer fixed on O.
