Correct Answer: 4 : 9
Given,
Circumference of 1st circleCircumference of 2nd circle=23
=> 2πr12πr2=23=> r1r2=23 => (r1r2)2=49
Area of 1st circleArea of 2nd circle= (r1r2)2=49

Your answer:-
ratio of the radii of two circles = 2:3
hence their circumference ratio is ....
2×(22÷7)×2 : 2×(22÷7)×3
cut out the similar no.s on the both side
Hence answer comes out to be
2:3
