Q. 14.5( 12 Votes )

# In a circle with centre P, chord AB is drawn of length 13 cm, seg PQ ⊥ chord AB, then find *l*(QB).

Answer :

We know that,

The perpendicular from the centre of a circle to a chord bisects the chord.

Therefore, it is given that,

AB=13 cm

PQ perpendicular to AB

|(QB) = AB/2

| (QB) = 13/2

| (QB) = 6.5 cm
