√10 IS BETWEEN 3.15 AND 3.17

OTHERWISE U JUST DRAW A LINE OF 7 CM
THEN MARK A POINT ON FIRST 5 CM
THEN FIND THE CENTER OF THE LINE AND DRAW A SEMI -CIRCLE.
THEN DRAW A LINE FROM THE 5 CM POINT TO THE CIRCLE
THAT LINE WILL BE ROOT 10

Draw a number line,
mark '0' as A
take 3 units from A
mark it B
now draw a perpendicular CB of 1 unit that meets AB at B
joinAC
by using pythagoras theorem we get, AC^2 =3^2+1^2
                                                              =9+1=10
so, AC= root of 10
draw an arc using the compass by fixing the needle at A which meets the numberline
then,the meeting point is root 10
