Answer:
x = 2.4; y = 3.2
Step-by-step explanation:
y = 3x - 4
2x + y = 8
2x + 3x - 4 = 8
5x - 4 = 8
5x = 12
x = 12 / 5
x = 2.4
y = 3(2.4) - 4
y = 7.2 - 4
y = 3.2
16.25pi.
You can get this by solving the cylinder volume formula for a cylinder with a 1.5 radius and then for the 1 radius of the empty portion. Then find the difference of the two.

Apply BODMAS
Open the brackets:
</span>-14 x 8 x 1/4 + (-22) = <span>-14 x 8 x 1/4 -22
Division
-14 x 8 x (1/4) - 22 = </span><span>-14 x 8 x 0.25 - 22
