Answer:
35
Step-by-step explanation:
2x² - 4x- (5 - 2x)
2x² - 4x - 5 + 2x
2x²-2x - 5 = f(x) - g(x)
Now use 5
The volume of a cylinder is =
V = π.R^(2).h
Let's to the first example:
R = 3cm
h = 32cm
Then,
1:
V = π.(3)^2.(32)
V = 288π.cm^3
This is correct.
Let's to the second example:
2:
R = 4cm
h = 12cm
Then,
V = π . (4)^2 . 12
V = 192 π cm^3
It is false.
___________
Let's to the 3 example:
R = Diameter / 2
R = 16 / 2
R = 8cm
And, h = 9cm
Then,
V = π . (8)^2 . 9
V = 576π cm^3
It is false
_____________
Let's to the 4 example:
R = 4cm
h = 18cm
Then,
V = π . (4)^2 . 18
V = 288π cm^3
This is correct
________________
Let's to the 5 and last example:
R = Diameter / 2
R = 12 / 2
R = 6 cm
h = 8cm
Then,
V = π . (6)^2 . 8
V = 288π
That's right too.
Then, The answers corrects to the your question are:
