#### Answer

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