(a) $I = 0.064~kg~m^2$ (b) $I = 0.032~kg~m^2$ (c) $I = 0.032~kg~m^2$

Work Step by Step

(a) $I = 4\times mr^2$ $I = 4\times (0.200~kg)[\sqrt{2}~(0.200~m)]^2$ $I = 0.064~kg~m^2$ (b) $I = 4\times mr^2$ $I = 4\times (0.200~kg)(0.200~m)^2$ $I = 0.032~kg~m^2$ (c) $I = 2\times mr^2$ $I = 2\times (0.200~kg)[\sqrt{2}~(0.200~m)]^2$ $I = 0.032~kg~m^2$
