Answer:
The answer to your question is ratio = 9
Step-by-step explanation:
Data
Circle 1 radius = 5''
Circle 2 radius = 15''
Process
1.- Calculate the area of circle 1
Area = πr²
Area = π(5)²
Area = 25π
2.- Calculate the area of circle 2
Area = πr²
Area = π(15)²
Area = 225π
3.- Calculate the ratio of the areas
ratio = 225π / 25π
= 9
