Question

represent root9.5 on number line

Answer 1

Answer:

Step-by-step explanation:

Step 1- Draw a line AB of length 9.5 cm

Step 2 - Mark a point C on the line such that BC =1 unit

Step 3- Find the mid point of AC. This can be done by making arcs as first yo hold a compass with pencil .Now from point A open the compass to a length that you think is more than the half of AC . Mark two arcs one upward an one downward. Do the same by taking point C ( towards point A) you will see that the arcs intersects on certain points let be P&Q .Now join P&Q you will get the mid point of AB. Taking O as the mid point now place the compass end on point O and pencil on A Now you have just rotate your hands and arc will be there to point C.

Step 4- Now from point B using scale and pencil you have to mark straight line above such that this line intersects the semi circle arc .Let say that it intersects on point D

Step 5- Now using compass taking one end at point B and one at point D make an arc to right side till it intersects the line .

So length of BE is that length which represents the desired reults i.e.√9.5
