Urgent with this math question also it would be great if someone can me with some other questions

Area=14.22π

Step-by-step explanation:

Area=πr²(C/360)

C  is the central angle in degrees

r  is the radius of the circle of which the sector is part.

Area = π(8)²(80/360)

Area=π(64)(0.2222)

Area=π(14.22)

Area=14.22π

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
