See my diagram
I'm assuming that your swimming pool is an oval or something like that
remember that the area of an oval is r₁r₂π where r₁ and r₂ are the 2 radii
so
we must do big oval-small oval
the radius is half of the diameter
calculating smalller oval area
it is 32 by 18
those are diameter
halve them
16 by 9
so the area is 16*9*pi or 144pi square feet
big oval area
add 3 feet to each side, so 6 feet total to each dimention
the big oval has diameters of 32+6 and 18+6 or 38 and 24
halve them to find the radii
19 and 12
the area is 19*12*pi or 228pi
so the area that is concrete=228pi-144pi=84pi squaer feet or about 263.89 square feet

Answer:
62 degrees
Step-by-step explanation:
Since lines i and k are parallel, angle b and h are interior angles and are equal to each other. Set up the equation by setting the two equal to each other.
8x-34=5x+2
Subtract 5x from both sides. (it cancels on the right side)
3x-34=2
Add 34 to both sides. (cancels on the left side)
3x=36
Divide both sides by 3.
x=12
Now plug it into either equation since they are equal. I'm gonna use the one for angle h so that it's less confusing.
5(12)+2
60+2
62
The measure of angle h is 62 degrees.

Step-by-step explanation:
----------------------------------------
The slope-intercept form formula is:
The stands for the slope and the stands for the y-intercept.
By looking at the graph, I can figure out that the y-intercept is -4 because y-intercept is where the lines cross the y-axis and in this graph, the line crosses the y-axis at (0,-4).
The slope is because to get to the ordered pair (3,0), from (0,-4), you would have to go up 4 and over 3 to the right so it's
So now, if we insert the values in the formula, it would be
