Answer 1

hey mate

ratio of radii=3:4

circumference=2pi r

circumference is directly proportional to radius

so ratio of circumference is3:4

hope it helps

please mark my ans as brainliest and follow me if it helps

Answer 2

r1/r2=3/4
we know that
circumference =
$2\pi \: r$
ratio = 2pi r1/ 2pi r2
3:4
