Answer:
Well, you didn't give any choices, but the equation is:
Cylinder Volume = PI * radius ^2 *height
Cylinder Volume = PI * 20 ^2 * 32
Cylinder Volume = PI * 400 * 32
Cylinder Volume = 40,212.39 cubic feet

Step-by-step explanation:
40192 ft^3
Given that the oil tank is in the shape of a cylinder. DIameter is 40 feet and height is 32 feet.
When diameter =40 feet, radius = 20 feet
We have formula for volume of cylinder as
V=
Thus we get volume as
see below
amount of water w
l liter of pure alcohol = 100% alcohol
solution is 45 % percent alcohol
total amount of fluid is w+l
(w+l)( .45) = l*.100
Distribute
.45w + .45 l = 1l
.45 w = 1l - .45l
.45 w = .55l
w = .55l / .45
w =11/9 l
Slope = (y2 - y1)/(x2 - x1)
Slope = (212 - 32)/(100 - 0)
Slope = 180 / 100
Slope = 18/10
Slope = 9/5
Answer
D. slope = 9/5
