Represent geometrically the following number on the number line: √8.1
Solution:
We have to locate √8.1 on the number line.
To represent the number √8.1 graphically,
First mark the given distance 8.1 units on the given line, from a fixed point A such that
AB = 8.1 units.
Mark a new point C at a distance of 1 unit from B such that BC = 1 unit.
Now, mark the point O which is the midpoint of AC.
Draw a semicircle with radius OC and center O.
Next, draw a line perpendicular to AC passing through B and intersecting the semicircle at D.
Now, BD = √8.1 units
Draw an arc with radius BD and centre B.
The arc intersects the number line at E such that
BE = BD = √8.1 units
