Question

the ratio of the area of circle with Centre O and radius 6 and circle with Centre P radius 12 is

Answer 1

area of circle =πrsquare
ratio=1/4

Answer 2

Raiot of both the circles:


$\frac{ar \: cirle(O,6,)}{ar \: \: circle(P,12)} \\ \\ = \frac{\pi {6}^{2} }{\pi {12}^{2} } \\ \\ = \frac{ {6}^{2} }{ {12}^{2} } \\ \\ = \frac{36}{144} \\ \\ = \frac{1}{4}$
Hence the required ratio is 1:4.
