Answer 1

hope u understand.....

Answer 2

hiii!!!

here's ur answer...

$let \: the \: radius \: be \: 3x \: and \: 4x \\ \\ ratio \: of \: both \: the \: circumference \: of \\ the \: circles = \frac{2\pi r }{2\pi \: r} \\ \\ = \frac{2\pi3x}{2\pi4x} \\ \\ = \frac{3x}{4x} \\ \\ =\frac{3}{4}\\ \\ ratio \: = \: 3 \: ratio \: 4 \\ \\ hope \: this \: helps....$
