Question

if r =13cm, and chord of circle's length 24cm the------------------- chord and centre​

Answer 1

Step-by-step explanation:

FIRST WE SHOULD KNOW PYTHAGORAS THEOREM

BY PYTHAHORAS THEOREM

TRIANGLE ABC IS FORMED BY RADIUS LINE FROM CENTRE AND HALF CHORD

THEN ONE SIDE IS 13 THAT IS RADIUS.THIS FORMS HYPOTENUSE.

LINE DRAWN FROM CENTRE BISECTS THE CHORD.

SO LENGTH OF BC = 12

BY PYTHAGORAS THEOREM

AC^2= AB^2 +BC^2

13^2= AB^2+12^2

169=144+AB^2

169-144=AB^2

25=AB^2

AB=root of 25

AB=5CM
