Question

the radius of a circle is 5 cm and
the distance of the chord from the
centre is 3 cm What is the length
of the chord​

Answer 1

Answer:

Perpendicular(3),half of chord(L/2),radius(5)make a right angled triangle. If the radius is 5cm and the chord is 3 cm from the centre, the length of the chord will be 2x4=8 cm.

Answer 2

Answer:

8cm

Step-by-step explanation:

L=Length of chord

h=distance of chord from centre

r=Radius of circle

$l = 2 \sqrt{ {r}^{2} - {h}^{2} }$

$l = 2 \sqrt{ {5}^{2} - {3}^{2} }$

$l = 2 \sqrt{25 - 9}$

$l = 2 \sqrt{16}$

$l = 2 \times 4$

$l = 8cm$

Hope u understand ,I have just used the basic Pythagoras theorem ...pls mark as brainliest if u get it
