Answer:
The answer is C. 2/3
Step-by-step explanation:
Hey there!!
- The area of a circle = πr²
The area is given as 196π
Hence,
196π = πr²
... r²= 196
... r = √196
... r = 14
<em>Hence, the radius is 14 cm. </em>

x - 1 x + 1
------ = --------------
x + 3 x + 6
if x = 9
8/ 12 = 10/15
12 (10) = 8(15)
120 = 120
so
answer is 9 (last choice)
