let the common factor be x...so
2:3 =>2x/3x....so the diameter of the first silver disc =2x and of the 2nd disc = 3x..so radius= 2x/2=x cm and of the 2nd disc =3x/2 cm..so ratio of the areas of the two silver disc =π *x^2 : π * (3x/2)^2 => 4:9

sunil9: 4:9 if d1:d2= 2:3 then r1:r2=2:3 so,area = 4:9
