I just purchased a swimming pool with the dimensions of 15 feet across and 42 inches deep. Yes it is a circle. I need to know how many gallons of water it will hold. I am having a tanker brought out and need to know how much they need to bring because they charge by the gallon to bring it out.

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.
By the way ... you'd be wise not to install the pool on the second floor.
That much water weighs a little over 19.3 tons !

y: the tens digit
The unit digit is twice the tens digit so:
x=2y
The two digit number:
10y+x
The two digit number doubled:
2(10y+x)
The reversed number:
10x+y
So:
2(10y+x)=10x+y+12
substitute x for 2y
2(10y+2y)=10(2y)+y+12
24y=21y + 12
3y=12
y=4
x=2y=2*4=8
So the number is 48.
a.
unit digit is y
tens is x
units is twice tens digit
y=2x
if it is doubled, it will be 12 more than reversed
20x+2y=12+10y+x
20x+4x=12+20x+x
3x=12
x=4
y=2x
y=2(4)
y=8
48 is the number
b. 8 times sum of digis is bigger than that number by 19
8(x+y)=19+10x+y
x=y-2
8(y-2+y)=19+10(y-2)+y
16y-16=19+10-20+y
y=3
x=y-2
x=3-2
x=1
the number is 13
c.
y=2x
2(10x+y)=9+10y+x
2(10x+2x)=9+20x+x
x=3
y=2x
y=3(3)
y=6
the number is 36
a. 48
b. 13
c. 36

The value of y intercept in the given equation of line is -6 or (0,-6) .
Given,
Equation of line :
2x + 5y = −30
Now,
y intercept is when the line crosses the y axis or when x = 0
Substitute x = 0 in the equation of line to get the y intercept value .
So,
2(0)+5y=-30
0+5y=-30
5y=-30
divide 5
y=-6
Thus,
value of y intercept is -6 or (0,-6)

set x=0
2(0)+5y=-30
0+5y=-30
5y=-30
divide 5
y=-6

numbers come out, a crank on the side, and some machinery inside.
You put a number in, turn the crank, and a number comes out ... usually
different from the one you put it.
If you do that enough times with enough different numbers, you can figure out
what machinery is inside.
Or, if you know what the machinery is, then when you put a number in,
you can always predict what number will come out.
