Helo my dear student i hope you will understand the discriptions i mentioned below, if you have any doubts feel free to ask me.please give me thumbs up if you are satisfied.
Here we are using the method of parallel axis theorem for determining the moment of inertia about any given axis for mixed geometries.
The used equations and worked details are given below
thank you...
