Question
Represent $\sqrt{9.3}$ on the number line.
✓
Answer
The distance 9.3 from a fixed point $A$ on a given line to obtain a point $B$ such that $A B=9.3$ units. From $B$ mark a distance of 1 unit and mark the new point as C . Find the mid-point of AC and mark that point as O . Draw a semi-circle with centre O and radius OC. Draw a line perpendicular to AC passing through B and interesting the semi-circle at D . Then $BD =\sqrt{9.3}$.
