Answer:

MARK ME THE BRAINLIEST

Step-by-step explanation:

A = π r²                                 C = 2πr

A α r²                                    C α r

A₁ : A₂ = 16 : 49

r₁² : r₂² = 16 : 49

r₁ : r₂ = 4 : 7                            

                                               C₁ : C₂ = r₁ : r₂

                                                           = 4 : 7
