Let the length of the circle be l

Angle of the circle 1 =65∘

Angle of the circle 2 =110∘

Let the radius be r1 and r2

l=r1θ

⇒r1×65×π/180

⇒13πr1/36

l=r2θl

⇒r2×110×π/180

⇒11πr2/18

Since l is same for both the circles

hope it helps..pls mark as brainliest

⇒13πr1/36=11πr2/18

⇒r1:r2=22:13

HOPE IT HELPS UH!!

PLEASE MARK AS BRAINLIEST

PLEASED TO HELP UH
