Question

what is the length of the chord which is at a distance of 4cm from the centre of a circle of radius 5cm​

Answer 1

Step-by-step explanation:

radius = hypotenuse of right angle triangle

distance = perpendicular

Chord= 2*base

H square = P square + B square

5 square = 4 square +B square

25 = 16 +B square

25 -16 =B square

√9 =B

3 cm =B

Chord=6cm
