Question

how far is is a a chord of length 8 cm from the centre of a circle of radius 5 cm

Answer 1

It will be 3cm away from the centre.

Answer 2

Answer:

3cm

Step-by-step explanation:

if the line from the center joing the chord is perpendicukar to the chord . Then it divides the chord into 2 equal parts

so, AC = BC

and 2AC = 8cm

AC = 4 cm

So ∆AOC forms a right angles triangle

therefore by Pythagores theorem

OC = 3cm
