Well, try to get the distance from the center of the circle to the center of one of the chords

For example the 10 cm chord.

line from circle center to middle of 10 cm chord hits chord at right angle, cuts it into two 5 cm legs

now have right triangle with leg 5 and hypotenuse 13 so other leg is sqrt(169-25)

or 12

so 12 is distance from center to the 10 cm chord.

Now do the distance to the 24 cm chord and add the two distances.
