Q

# Represent square root 4 point 3 on the number line

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

Draw a line segment OB of 9.3 unit. Then, extend it to C so that BC = 1 unit. Find the mid-point D of OC and draw a semi-circle on OC while taking D as its centre and OD as the radius. Now, Draw a perpendicular to line OC passing through point B and intersecting the semi-circle at E. Now, Take B as the centre and BE as radius, draw an arc intersecting the number line at F.  the length BF is $9\sqrt{3}$ units.
