A sphere of moment of inertia 3.5 kg m2

, rotates about its diameter with a constant angular speed of

2 rad/s. Find the angular momentum.

Linear momentum (p) is defined as the mass (m) of an object multiplied by the velocity (v) of that object: p = m*v. With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.
