    The area of a circle of radius 5 is numerically what per cent of its circumference?

    A) 200                  

    B) 225

    C) 240                              

    D) 250

    Correct Answer: A

    Solution :

    We know that, Circumference \[=2\pi r\]             \[=2\times \frac{22}{7}\times 5=\frac{220}{7}\] Area \[=\pi {{r}^{2}}=\frac{22}{7}\times 25=\frac{550}{7}\] \[\Rightarrow \] Required answer\[=\frac{550}{7}\times \frac{7}{220}\times 100=250\]
