Answer:

Step-by-step explanation:

given that the ratio of area of circle

 i.e πr^2/πR^2=49/64

       there fore r^2/R^2 = 49 /64

                 r/R = 7/8

     we know that the circmference of circle = 2pie r

               ⇒2πr/2πR=7/8

       there fore the ratio of there circmfarence = 7/8
