3x + 6 + x + 2 = 180
4x = 180 - 8
4x = 172
x = 43
A = 3x + 6 = 3×43 + 6 = 129 + 6 = 135
The surface area, I believe, is 584,064.
Broken down, the formula is really 312 x 312 x 6
312 x 312 = 97,344 97,344 x 6 = 584,064......... There is your answer.
SA = 584,064

Step-by-step explanation:
Area of sector of circle with central angle measuring n degrees and radius r:
![area = \dfrac{n}{360^\circ}\pi r^2](https://tex.z-dn.net/?f=%20area%20%3D%20%5Cdfrac%7Bn%7D%7B360%5E%5Ccirc%7D%5Cpi%20r%5E2%20)
![area = \dfrac{80^\circ}{360^\circ} \times 3.14 \times (5.5~in)^2](https://tex.z-dn.net/?f=%20area%20%3D%20%5Cdfrac%7B80%5E%5Ccirc%7D%7B360%5E%5Ccirc%7D%20%5Ctimes%203.14%20%5Ctimes%20%285.5~in%29%5E2%20)

The circumference of a circle is the distance around the outside of the circle. The diameter is the distance across the circle. It must pass through the center or the circle. For any circle, regardless of diameter, there is a consistent ratio between the circle's circumference and the length of its diameter.
