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 $A C$ and mark that point as $O$. Draw a semicircle with centre $O$ and radius $O C$. Draw a line perpendicular to $A C$ passing through $B$ and interesting the semi-circle at $D$ . Then $BD =\sqrt{9.3}$.
