    Help! I'm Not Sure What I Did Wrong in Evaluating MOI of a Sphere

    This is the temporary brief explanation I drew on my phone: The angle here can be found simply with some subtraction and addition of some polygon angles. This is the actual relation between ##dh## and ##Rd\theta##. Thank you all brilliant and kind minds so so much for your inputs. I have...

    I know I must have done something wrong somewhere here, but I cannot figure out exactly which one Answer is supposed to be (2/5)MR2 Whatever disaster I have in the last image does not evaluate closely to that at all. I'm not looking for another way to find the MOI of solid sphere, I would...
