Question

Chord PQ of a circle has length equal to radius of circle,if the distance of chord from the centre of a circle =5√3,then the value of chord=radius =​

Answer 1

Answer:

3/2

Step-by-step explanation:

Answer 2

Answer:

23

Given−PQ is a chord of a circle with centre O such that

OP = OQ = r =PQ when r is the radius ofthe circle.

To find out h=ON,the distance of PQ from O.

Solution−

ΔOPQis equilateral since all its sides = r.

Now heigh to fan equilateral triangle with side

=a is 23

a an dit bisects the base a trightangle.

Here a = r.

∴Theheight = ON = h= 23

But ON is the distance of the chord PQ from Osince

the perpedicular distance of a chord from the centre

bisects the chord at right angle.

So h=ON= 23
