X = -6y - 12
4x + 5y =-39
4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3
x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6
(x, y) = (6, -3)

the answer is 42.77...........................................
we know that
The volume of a cylinder is equal to

where
r is the radius of the base
h is the height of the cylinder
In this problem

For 
<u>Find the value of h</u>


<u>Find the volume of the cylinder</u>


therefore
<u>the answer is</u>
The volume of a cylinder is equal to
