A) \[\text{Rs}.\text{1232}0.00\]
B) \[\text{Rs}.\text{3}0\text{8}0.00\]
C) \[\text{Rs}.\text{616}0.00\]
D) \[\text{Rs}.\text{154}0.00\]
Correct Answer: B
Solution :
| [b] Radius of each circle \[=7cm\] |
| \[\therefore \] Area of one circle |
| \[=\pi {{r}^{2}}=\frac{22}{7}\times 7\times 7=154c{{m}^{2}}\] |
| \[\therefore \]Area of four such circles \[4\times 154=616c{{m}^{2}}\] |
| So, cost of painting the circles |
| \[=Rs.(5.00\times 616)=Rs.3080.00\] |
