A chord is 2cm from the centre of a circle. if the ratius of the circle is 5cm, find the length of the chord

Draw a diagram, including the radii to the ends of the chord. Draw the radius perpendicular to the chord. You now have two right triangles with one leg=1 and hypotenuse=5. Half the length of the chord is √24.

Err, I mean one leg=2. So half the chord has length √21
