Question

distance of chord a b from the centre of circle is 5 cm length of Chord ab is 24 cm find the diameter of circle​

Answer 1

Answer:

120cm

Step-by-step explanation:

by Pythagoras theorem

ob²=nb²×on²

= 144× 25

= 3600

= 60

so, radius of circle is 60

therefore, diameter.....120

Answer 2

Given:

The distance of the cord ab from the centre of the circle = 5 cm

The length of the cord = 24 cm

To find:

The diameter of the circle.

Solution:

The radius of the circle, the chord and the distance of the chord from the centre will form a right-angled triangle and hence we can use Pythagoras theorem to solve this problem.

Thus, the radius of the circle will be:

12² + 5² = radius²

144 + 25 = radius²

radius² = 169

radius = 13 cm

Thus, the diameter of the circle will be:

= radius× 2

= 13 cm ×2

= 26 cm

Thus, the diameter of the circle will be 26 cm.
