Answer:
C
Step-by-step explanation:
area is pi X radius squared
radius is half of diameter
so it is pi X 6²
wich is pi X 36
The value of y would be 60
The way you would solve this is by plugging in 7 for x.
After you plug in the 7 for x you would have to multiply 7 by 4 to get 28.
Next you would add 28 to 32 to get 60.
Your final answer should be y=60
