Hello,
The formula for finding the circumference of a circle is $2 \pi r$ where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius: $2 \pi 4=8 \pi$ . We are told to use 3.14 for $\pi$ so we get $8(3.14)=25.12$ . Therefore, the circumference is 25.12 meters.

$\\ \sf\longmapsto \dfrac{8}{12}=\dfrac{x}{9}$

$\\ \sf\longmapsto 12x=8(9)$

$\\ \sf\longmapsto 12x=72$

$\\ \sf\longmapsto x=\dfrac{72}{12}$

$\\ \sf\longmapsto x=6$
