Question

find the length of a chord which is at a distance of 5 cm from the centre of a circle of radius 10cm​

Answer 1

Answer:

In circle if radius 10cm,find the length of a chord which is at a distance of 5cm from its center. 2.

Step-by-step explanation:

Let AB be a chord of a circle with centre O and radius 13 cm. Draw OL⊥AB. Join OA.

Here, OL=5 cm,OA=13 cm.

In right triangle OLA,

OA

=OL

+AL

+AL

AL

=144

AL=12

Since the perpendicular from the centre to a chord bisects the chord. Therefore,

AB=2AL=2×12=24 cm
