Question

If the areas of two circles are in the ratio 169:196 then the ratio of their radius is

Answer 1

Answer:

Here, I'm giving the simplest way to solve this question; simple and easy:

$\tt{\frac{169}{196} = \frac{\pi (r_{1}) ^{2}}{\pi( r_{2} )^{2}}}$

=> $\tt{\frac{13}{14}}$

Formula used:

Area of a circle = $\tt{\pi r^{2}}$

Answer 2

Answer:

areaa of one circle next step areaa of second circle then result is added
