Question

represent root 9.3 on number line​

Answer 1

Step-by-step explanation:

*draw a line and mark a point A on it

*mark a point B on the line drawn in step 1 such that AB=9.3cm

*mark a point C on AB produced such that BC = 1unit

*find mid point of AC .let the midpoint be o.

*taking o as the centre &oc=oa as radius draw a semi circle.also,draw a line passing through B perpendicular to OB. suppose it cuts the semicircle at D

*taking B as the centre and BD as radius drawn an arc cutting OC produced at E .point E so obtained represents 9.3

Answer 2

Step-by-step explanation:

1. firstly draw a line 9.3 and name it point AB
2. now extend 9.3 by adding 1cm it becomes 10.3cm and name it point C
3. now draw a semicircle by doing half of 10.3
4. now draw a perpendicular on point B and name it point D
5. now taking B as a center and D as radius draw an arc
6. give it name as P
7. so P is 9.3
