Ответ:
The area of circle 1 is 9 times greater than area of circle 2.
Step-by-step explanation:
Given that:
Radius of circle 1 = 12
Area of circle 1 = πr²
Area of circle 1 =![3.14*(12)^2 = 3.14*144](/tpl/images/1020/5562/0addc.png)
Area of circle 1 = 452.16
Radius of circle 2 = 4
Area of circle 2 =![3.14*(4)^2 = 3.14*16](/tpl/images/1020/5562/c794d.png)
Area of circle 2 = 50.24
Let,
x be the number of times circle 1 is bigger than circle 2.
Area circle 1 = x * Area circle 2
Hence,
The area of circle 1 is 9 times greater than area of circle 2.
