Radius = 130/(2) = 65 cm

Chord = 66 cm

half chord = 33 cm

The centre forms an isosceles triangle with the chord, with the two equal sides the radii of the circle.

Consider the right triangle which forms half of the isosceles triangle.

distance from centre to the chord = h

where h²+33²=65²

Solve for h. (Hint: h is an integer)
