A) 200
B) 225
C) 240
D) 250
Correct Answer: D
Solution :
We know that, circumference \[=2\pi r=2\times \frac{22}{7}\times 5=\frac{220}{7}\] Area \[=\pi {{r}^{2}}=\frac{22}{7}\times 25=\frac{550}{7}\] \[\therefore \] Required answer \[=\frac{550}{7}\times \frac{7}{220}\times 100=250%\]You need to login to perform this action.
