What is the angular momentum (in kilogrammeter^2/second) of a 300.0 g ball rotating on the end of a string in a circle of radius 1.87 m at an angular speed of 1.50 rad/s? Is there certain equations to find angular momentum for different shapes?

drwls,
Treat the ball as a point mass, since it is at the end of a striking much larger than the sphere.
The angular momentum is
M V R = M R^2 w
Where w is the angular velocity
