Given:

Diameter of the circle = 26 cm

Radius of the circle (r) = 26/2 = 13 cm

Length of the chords = 10 cm each

Distance between the two chords = h cm

Formula used:

For a chord of length 2a, the perpendicular distance from the center of the circle is given by:

d = √(r2 - a2)

Where r = radius, a = half of the chord length

Calculation:

Half of the chord length (a) = 10/2 = 5 cm

Using the formula for the perpendicular distance:

d = √(132 - 52)

d = √(169 - 25) = √144

⇒ d = 12 cm

The distance between the two chords = 2d = 2 × 12 = 24 cm

∴ The value of h is 24 cm.
