Represent √9.3 on number line.

1. Mark a line segment OB = 9.3 on number line.

2. mark point C at a distance of 1 unit from B.

3. Find midpoint of OC and mark it D.

4. Draw a semicircle on OC while taking D as its centre. Draw a perpendicular to OC passing through B which intersects at E.

Taking B as a centre and BE as radius, draw an intersecting number line at F.
