Question

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

Answer 1

Steps:

1) Draw a line segment AB of length $9.3$ units.

2) Extend the line by 1 unit more such that $BC=1$ unit .

3) Find the midpoint of $OC$ say $B$. With $BC$ as radius, draw a semi circle.

4) Draw a line BD perpendicular to AB and let it intersect the semicircle at point D.

5) Draw an arc $DE$ such that $BE=BD$.

Therefore, BE=$\sqrt{9.3}$ units
