Diameter1 = 7cm
Diameter2 = 12cm
Circumference 1 = 22/7 ☓ 7 = 22cm
Circumference 2 = 22/7 ☓ 12 = 264/7 cm
Now ratio of circumference 1 to 2 =
22 ☓ 7/264
= 7/12
Ratio = 7 :12

Answer:
Diameter1 = 7cm
Diameter2 = 12cm
Circumference 1 = 22/7 X 7 = 22cm
Circumference 2 = 22/7 X 12 = 264/7 cm
Now ratio of circumference 1 to 2 =
22 X 7/264
= 7/12
Ratio = 7:12
