A) \[2.16\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[3.62\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[3.94\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[4.15\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
\[4r=a\sqrt{2}\] \[a=\frac{4r}{\sqrt{2}}=\frac{4\times 1.28}{\sqrt{2}}\,\overset{\text{o}}{\mathop{\text{A}}}\,=3.62\overset{\text{o}}{\mathop{\,\text{A}}}\,\]You need to login to perform this action.
