- mark a line segment OB=9.3 on number line.
- mark point C at a distance of 1 unit from B.
- find the mid point of OC and mark it point D.
- draw a semi circle on OC taking centre at D as it's centre .
- draw a perpendicular to line OC passing through point B.
- let it intersect the semi circle at E.
- taking B as centre and BE as radius,draw an arc intersecting number line at f
- BF is √9.3.
