Question

How to represent √9.3 on number line

Answer 1

Answer: HEY MATE UR ANSWER PLS MARK ME AS THE BRAINLIEST PLZZ

Step-by-step explanation:

Draw a line AB measuring 9.3 units, or 9.3 cms.

From point B, add 1 cm, mark the point as ‘C’

Take compasses and bisect the line, mark the point of bisection as ‘O’. I hope you’re familiar with bisecting a line with compasses.

Measure ‘AO’, ‘AO’ acts as radius, with ‘O’ as centre, draw a semicircle.

From ‘B’, draw a line perpendicular ‘AB’, touching the semicircle drawn at a point, say, ‘D’. Mark it as sqrt(9.3).

Take compass pointer on ‘B’, pencil on ‘D’, draw an arc on the number line.

The point which intersects Number Line is sqrt(9.3).

You can follow the same procedure for square root of any number.
