A) \[11:12\]
B) \[21:33\]
C) \[22:33\]
D) \[14:11\]
Correct Answer: D
Solution :
(d): \[2\pi \times 42\] length becomes perimeter of square. Area (Circle) \[=\pi \times {{42}^{2}}\] Side of square \[=\frac{2\pi \times 42}{4}=21\pi \Rightarrow \]Area (square) \[={{\left( 21\pi \right)}^{2}}\] \[\therefore \,\frac{Area\,\left( circle \right)}{Area\,\left( Square \right)}=\frac{\pi \times {{42}^{2}}}{{{\pi }^{2}}\times {{21}^{2}}}=\frac{4}{\pi }=\frac{4}{22/7}=\frac{14}{11}\]You need to login to perform this action.
