Answer:

You have a rectangular pool 15 X 30 X 5 feet

The floor of the pool is 15X30 = 450 ft2

Two sides are 5X15 = 2(75) = 150 ft2

Two sides are 5X30 = 2(150) = 300 ft2

Total area to be painted: 900 ft2

(900 ft2)/(250 ft2/gal) = 3.6 gallons

Since we can't purchase .6 gallons we

must purchase 4 gallons of paint

The volume of the pool is 15X30X5 = 2250 ft3

1 ft3 = 7.48 gallons

2250(7.48) = 16,830 gallons of water

To solve this we are going to use the formula for the area of a circle: A= \frac{1}{4} \pi d^2
where
A is the area of the circle 
d is the diameter of the circle 

We know from our problem that the area of our circle is 10 inches long, so d=10in. Lets replace that value in our formula to find A:
A=\frac{1}{4} \pi (10in)^2
A=78.54in^2

We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.

I'm assuming that you meant 4x+1=3x?

Subtracting 4x, we get 1=-x.  Multiplying by -1, we get x=-1 as the solution.
