The radius is 20cm and the chord is 20 cm.
Draw the radii to each end of the chord, you will see that you have an equilateral triangle, so the chord subtends a central angle of 60°, which is 1/6 of the circumference.
That should give you enough of a clue to proceed.
In a circle of diameter 40cm,length of chord is 20 cm. Find the length of minor arc of the chord.
