Answer:

Step-by-step explanation:

XY = 3x – 1, YZ = 5, and XZ = 5x – 8,

We know that XY + YZ = XZ, so

3x - 1 + 5 = 5x - 8

3x + 4 = 5x - 8

3x + 12 = 5x

12 = 2x

6 = x

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

$x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3$

$\pi\approx3.14$

Therefore

$x=(75)(3.14)=235.5\ in^3$
