A) \[11:12\]
B) \[21:33\]
C) \[22:33\]
D) \[14:11\]
Correct Answer: D
Solution :
Length of wire \[=2\pi \times 42\] \[=84\,\pi \,cm\] Let x be the side of the square. We have, \[4x=84\,\pi \Rightarrow \,\,x=21\,\pi \] Area of the circle: Area of the square \[=\pi \,{{(42)}^{2}}:{{(21\pi )}^{2}}\] \[=4:\pi =4:\frac{22}{7}=14:11\]You need to login to perform this action.
