represent root 9.3 on the number line
draw a line AB of 9.3cm .then extend to c of 1cm.now find the midpoint AC with the help of a compass.draw a straight line perpendicular to AC from that point.name the point E and the centre point as D.name the point E such that AD = DE.now draw a semi circle from A to C.braw a perpendicular line from B such that it touches the semi circle.name point at where the straight line from B touches the semicircle as F.with F cut an arc.the point at witch the arc meets the number line is the root of 9.3
To locate on the number line, we have to follow the steps given below.
(1) Draw a line AB = 9.3 units and BC = 1 unit.
(2) Find the mid-point of AC and mark it as O. Taking O as the centre and OA as the radius, draw a semi-circle.
(3) From B, draw a perpendicular to AC. Let it meet the semi-circle at D. Taking B as the centre and BD as the radius, draw an arc that intersects the line at E.
Now, the distance BE on the line is units.
