# Represent $$\sqrt{9.3}$$ on the number line.

Firstly we draw AB = $$\sqrt{9.3}$$ units. Now, from B, mark a distance of 1 unit.

Let this point be C. Let O be the mid-point of AC. Now, draw a semi-circle with centre O and radius OA.

Let us draw a line perpendicular to AC passing through point B and intersecting the semi-circle at point D.

$$\therefore$$ the distance BD = $$\sqrt{9.3}$$ units.

Draw an arc with centre B and radius BD which intersects the number line at point E, then the point E represents $$\sqrt{9.3}$$ .
