A) \[400\]
B) \[600\]
C) \[800\]
D) \[1000\]
Correct Answer: C
Solution :
Let the radius of the larger circle be\[R\], then radius of smaller circle\[=\frac{R}{2}\] \[\therefore \] \[\pi \frac{{{R}^{2}}}{4}=200\Rightarrow \pi {{r}^{2}}=4\times 200\] \[\Rightarrow \] \[\pi {{R}^{2}}=800\] Here, area of larger circle\[=800\,\,c{{m}^{2}}\]You need to login to perform this action.
