Question

In a circle of radius 5cm, a chord is of length 6cm. Find the distance of the chord from the centre of the circle.

Answer 1

draw a line from cente to mid of chord

now this is a right anhle triangle with Hypotns 5 cm and base 3 cm
, by using pythagoras,
H²=P²+B²
P² = 5²-3³
P² = 25 - 9
P² = 16 and
P is 4 cm which is distance of chord from centre
