Answer:
x=1
Step-by-step explanation:
If V is the midpoint of the line UW, that would mean that there's an equal distance between UV and 9x. So, the value of UV and VW would eed to be the same.
x+8=9x
8=8x
x=1
Convert to cylindrical coordinates:
![x=x](https://tex.z-dn.net/?f=x%3Dx)
![y=r\cos\theta](https://tex.z-dn.net/?f=y%3Dr%5Ccos%5Ctheta)
![z=r\sin\theta](https://tex.z-dn.net/?f=z%3Dr%5Csin%5Ctheta)
Then
is the set of points
such that
,
, and
or
.
Now
![\displaystyle\iiint_E5x\,\mathrm dV=5\int_0^{2\pi}\int_0^1\int_{7r^2}^7xr\,\mathrm dx\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{245\pi}3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Ciiint_E5x%5C%2C%5Cmathrm%20dV%3D5%5Cint_0%5E%7B2%5Cpi%7D%5Cint_0%5E1%5Cint_%7B7r%5E2%7D%5E7xr%5C%2C%5Cmathrm%20dx%5C%2C%5Cmathrm%20dr%5C%2C%5Cmathrm%20d%5Ctheta%3D%5Cboxed%7B%5Cfrac%7B245%5Cpi%7D3%7D)
