Question

In a circle with centre P, chord AB is drawn of length 13 cm,set PQ chord AB then find (QB)​

Answer 1

Answer:

some hints are missing here.

is the PQ is a perpendicular drawn to chord AB?

Answer 2

Answer:

$\fbox \red { The Length of QB is 6.5 cm }$

Step-by-step explanation:

Question:-

A circle of centre P is drawn.

Chord AB is drawn of Length 13 cm as shown in the above attached figure.

EXPLANATION:-

Let Q is the point on AB

Such that PQ is perpendicular to AB

We know that , The chord is bisected by a line passing through the centre and perpendicular upon it.

Here :-

Chord PQ is perpendicular to AB

$\bf \huge \red So \: , AQ = QB = \frac{AB }{2} \\ \\ \bf \huge \purple = > \purple AQ = QB = \frac{13}{2} \\ \\ \bf \huge \green = > 6.5 \: cm \:$

$\fbox \red { Hence The Length of QB is 6.5 cm }$
