    12.287 cm

    Step-by-step explanation:

    32 degrees = 32 * (π/180) rad/degree = 0.5585 rad

    The chord length that the bob sweeps equals to the product of chord angle and the swinging radius, aka pendulum length

    = 0.5585 * 22 = 12.287 cm.

    So the bob swings a distance of 12.287 cm at an angle of 32 degrees.
