Question

show root 6.3 on number line​

Answer 1

Draw a line segment AB = 6.3 units and extend it to C such that BC = 1 unit.

Find the midpoint O of AC.

With O as centre and OA as radius, draw a semicircle.

Now, draw BD perpendicular to AC, intersecting the semicircle at D.

Then, BD = root 6.3 units.

With D as centre and BD as radius, draw an arc, meeting AC produced at E.

Then, BE = BD = root 6.3 units.
