Hey !!
Ratio of radii of Circle ∆1 and ∆2 = 3:5
Let radius of circle ∆1 = 3x
and that of circle ∆2 = 5x
[Where 'x' is any constant natural number]
Circumference of a Circle = 2πr
Circumference of circle ∆1 = 2*π*3x = 6πx
and that of circle ∆2 = 2*π*5x = 10πx
Hence ratio of circumference of circle ∆1 and ∆2 = 6πx : 10πx
= 3 : 5 Ans.
Hope it helps :)
