A) \[\frac{\text{73}}{\text{2}}\text{M}{{\text{R}}^{\text{2}}}\]
B) \[\frac{\text{181}}{\text{2}}\text{M}{{\text{R}}^{\text{2}}}\]
C) \[\frac{\text{19}}{\text{2}}\text{M}{{\text{R}}^{\text{2}}}\]
D) \[\frac{\text{55}}{\text{2}}\text{M}{{\text{R}}^{\text{2}}}\]
Correct Answer: B
Solution :
\[I=\left( \frac{M{{R}^{2}}}{2} \right)+6\left[ \frac{M{{R}^{2}}}{2}+M{{(2R)}^{2}} \right]=\frac{M{{R}^{2}}}{2}+6\left[ 4.5\,\,M{{R}^{2}} \right]\] \[I=27.5\,\,M{{R}^{2}}=\frac{55}{2}M{{R}^{2}};{{I}_{P}}=\frac{55}{2}M{{R}^{2}}+(7M){{(3R)}^{2}}=\frac{181M{{R}^{2}}}{2}\]
