of the cylinder is 15-ft, and the height of the cylinder is 42 inches.
Here are the tools you'll need:
-- Volume of a cylinder = (pi) (radius squared) (height)
-- Radius = 1/2 diameter = 7.5 feet
-- Keep everything in the same units. Depending on which unit
you prefer, 7.5 feet = 90 inches, and 42 inches = 3.5 feet.
I like inches and cubic inches, because I remember that
1 gallon = exactly 231 cubic inches.
Volume of the cylinder = (pi) (radius squared) (height)
Volume = (pi) (90 squared) (42) = (pi) (8,100) (42) = 1,068,769.8 cubic inches
1,068,769.8 / 231 = 4,626.7 gallons
===================================
Slightly easier:
about 7.48 gallons = 1 cubic foot
Volume = (pi) (7.5-ft squared) (3.5-ft) = 618.5 cubic feet
(618.6 cubic-ft) x (7.48 gallons per cubic-ft) = 4,627.1 gallons
The results are not identical, but don't panic. They are equal
to within about 51 ounces (0.009 percent). The tanker will either
spill or evaporate more than that during the process of the delivery.

Answer:
Option B. x = -1, 19
Step-by-step explanation:
The given equation is x² - 18x = 19
We can get the value of x by factorizing the expression or by quadratic formula.
We will try to factorize the equation first. If we find no factors then we will apply quadratic formula to get the value of x.
x² - 18x - 19 = 0
x² - 19x + x - 19 = 0
x(x - 19) + 1(x - 19) = 0
(x - 19)(x + 1) = 0
x = 19, -1 will be the solutions.
So there is no need to apply quadratic formula.
Option B. x = -1, 19 is the answer.
REMEMBER THIS
ok
first, make sure that a is 1
done
now take 1/2 of b and square it
-18/2=-9, (-9)^2=81
add that to both sides
x²-18x+81=19+81
x²-18x+81=99
factor perfect square
(x-9)²=100
square root both sides
don't forget positive and negative root
x-9=10
x-9=-10
ad 9 to both sides
x=19
x=-1
answer is -1; 19
