    L = 0.5*M*R^2 * w

    Explanation:

    Solution:-

    - The angular Momentum (L) of a rigid body about any axis is given by the following relationship:

    L = I*w

    Where,

    I : Moment of inertia of the rigid body

    w: The angular speed of the rigid body.

    - The moment of inertia (I) for a disc is given by:

    I = I_disc

    I = 0.5*M*R^2

    Where,

    M : Mass of the disc

    R : The radius of the disc.

    - Hence, the Angular momentum (L) of the disc rotating about an axle is:

    L = 0.5*M*R^2 * w
