Question

The length of a chord of a circle is 20 and its distance from the centre of the circle is 24. Find the diameter of the circle​

Answer 1

Answer:

Step-by-step explanation:

We know that the chord is perpendicularly bisected by the the line from the centre.

length of chord=20

length of chord from the centre=24

d=2×radius

By pythagoras theorem,

ab^2+cb^2=ac^2

24^2+10^2=ac^2

576+100=ac^2

676=ac^2

26=ac

therefore 2r=d

2×26=52

d=52
