23) Set up and evaluate an in tegral in spherical Coordinates to find the volume of the solid Z= inside x²+y² + 2² = 9, outside 2 = √x² + y², and above the xy-plane

Please give an explanation to how you assigned the spherical coordinates

Use spherical coordinates to find the volume of a sphere of radius 2 from which a central cy tinder of radius 1 has been removed.
