Volume =
![\pi {r}^{2} h](https://tex.z-dn.net/?f=%5Cpi%20%7Br%7D%5E%7B2%7D%20h)
![r = \sqrt{678.59 \div 6}](https://tex.z-dn.net/?f=%20r%20%3D%20%5Csqrt%7B678.59%20%5Cdiv%206%7D%20)
multiply r by 2 and you will get diameter
Y = 8x - 2
y = 9x - 7
8x - 2 = 9x - 7
- 8x - 8x
-2 = x - 7
+ 7 + 7
5 = x
y = 8x -2
y = 8(5) - 2
y = 40 - 2
y = 38
(x, y) = (5, 38)
The answer is C.
