want to make $25?

my mom is studying for her statics exam. today she was particularly frazzled. at one point she looked at me and said, "bandy, if you can figure out this problem, i'll give you fifty dollars!" i laughed to myself - if this was a statistics problem, we all know i'd ace it (being a statistics professor and all). engineering statics? prob not. i gave it a look and i don't know how to do it. 

if YOU can tell me how to do it, ill go halves with you..(assuming she really gives me the $25) here it is:

The machine element shown is fabricated from steel. Determine the mass moment of inertia of the assembly with respect to (a) the x axis (b) the y axis & (c) the z axis. (The specific weight of steel is 0.284lb/in^3)

...have at it and we'll both be RICH. (hey, $25 is like a life savings for a dog!!)
