Answer 2

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Solution~~}}}}$

let the radius of the circles are r1 and R2

now...

$\frac{2\pi \: r1}{2\pi \: r2} = \frac{r1}{r2} = \frac{4}{9}$

therefore the area will be in the ratio of...

$= > \frac{a1}{a2} = (\frac{r1}{r2} ) {}^{2} = ( \frac{4}{9} ) {}^{2} \\ = > \frac{a1}{a2} = \frac{16}{81}$
