Solution

Step 1: Drawing a circle of radius $4.2 c m$ .

Mark a point O and measure distance $4.2 c m$ on compass with the help of a ruler.

Put the pointed end of the compass at O and trace the circle.

Step 2: Assigning a special name to AB.

Mark a point 𝐴 on the circle and join O to A.

Extend the line OA such that it meets at point B on circumference of the circle.

AB is a line segment formed by joining two distinct point on the circumference of the circle such that it passes from the center as well.

Hence, AB is the diameter of the circle.
