Calculate the moment of inertia of the thin spherical shell having a m

1.	Calculate the moment of inertia of the thin spherical shell having a mass of 3.3 kg and diameter of .6 cm.(a) .00125 kgm^2(b) .00196 kgm^2(c) .00145 kgm^2(d) .00178 kgm^2I got this question by my school principal while I was bunking the class.I need to ask this question from Energy Relations During Starting in section Starting of Electric Drives
Answer» Correct choice is (b) .00196 kgm^2 To explain: The MOMENT of inertia of the thin spherical shell can be calculated USING the formula I=mr^2×.66. The mass of the thin spherical shell and diameter is given. I=(3.3)×.66×(.03)^2=.00196 kgm^2. It depends UPON the orientation of the ROTATIONAL axis.
