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 kg and diameter of 66 cm.(a) .2156 kgm^2(b) .2147 kgm^2(c) .2138 kgm^2(d) .2148 kgm^2This question was posed to me during a job interview.I would like to ask this question from Starting in chapter Starting of Electric Drives
Answer» The correct answer is (a) .2156 kgm^2 For explanation: 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)×.66×(.33)^2=.2156 kgm^2. It depends UPON the ORIENTATION of the rotational axis.
