Question

the radius of a circle is 13 cm and the length of one of its chord is 10 cm find the distance of the chord from the center

Answer 1

Step-by-step explanation:

1. draw a graph ,draw a circle of 13cm u get x =5and y=12
2. draw a chord 10
3. u get coordinates use distance formula passes from origin u get distance between chord from crnter

Answer 2

Answer:

Your question...

The radius of a circle is 13 cm and the length of one of its chord is 10 cm find the distance of the chord from the center..

My answer...

Let AB be a chord of a circle with centre O and radius 13 cm such that AB = 10 cm.

From O, draw OL ⊥ AB. Join OA.

Since, the perpendicular from the centre of a circle to a chord bisects the chord.

∴ AL = LB = ½ AB = 5 cm

Now, in right triangle OLA, we have

OA2 = OL2 + AL2

⇒ 132 = OL2 = 52

⇒ 132 – 52 = OL2

⇒ OL2 = 144

⇒ OL = 12 cm

Hence, the distance of the chord from the centre is 12 cm....
