Mark the correct A. 22 : 13

B. 11 : 13

C. 22 : 15

D. 21 : 13

Answer :

Let radius of two circles be the r1 and r2

Let θ1 and θ2 be the subtend angles of arcs of two circles


i.e. θ1=65° and θ2=110°


We know that arc length,


l = r × θ


Here, arc lengths of two circles are same.


r1×θ1=r2×θ2




r1 :r2 =22:13
