I assume that 4.4 is the diameter,please do correct me if i am wrong.
To get the area of the circle,the formula is 丌r^2
to find the radius,we need ro devide the diameter by 2
thus the equations is

Therefore the answer is B.15.2
hope it helps!
I don't know if anyone know say him answer
Answer:
The answer is the third option from the top:
0, 0, 11, 15, 26, 32, 45, 46, 46, 46, 60, 71, 84, 88
Angle 2 is 143
angle 4 is 37
angle 7 is 143
angle 8 is 37
Y and the angle marked 60 degrees are internal alternate angles and are equal
so y = 60
