It doesn't say if you need your answer in inches or feet but either way you have to convert the diameter to inches or the thickness of mulch to feet.
I did it both ways.
v = pi r^2 h is the formula for volume of a circular cylinder. This is the shape you would end up with because of the thickness of the mulch.
In feet: v=pi(6^2)(1/3); v = pi(36)(1/3); v=pi(12) or 12pi ft^3; If you have to use 3.14 as pi then the answer would be 37.68 ft^3.
In inches: v=pi(72^2)(4); v=pi(5184)(4); v= pi(20,736) in^3; if you have to use 3.14 as pi then the answer would be v = 65,111.04 in^3
Answer:
x = -2
Step-by-step explanation:
Step 1: Add 10 to both sides.
Step 2: Check if solution is correct.
Therefore, x = -2.

Start of by doing -2-1
Answer:
x/7+13=32
Step-by-step explanation:
work backward so subtract 13 from 32 and get 19 multiply it by 7 and get 133, to make sure your answers right just substitute 133 back into the equation
Y = -x² + 3x - 1
x = 2y - 1
x = 2(-x² + 3x - 1) - 1
x = 2(-x²) + 2(3x) + 2(-1) - 1
x = -2x² + 6x - 2 - 1
x = -2x² + 6x - 3
<u>- x - x </u>
0 = -2x² + 5x - 3
x = <u>-(5) +/- √((5)² - 4(-2)(-3))</u>
2(-2)
x = <u>-5 +/- √(25 - 24)</u>
-4
x = <u>-5 +/- √(1)
</u> -4
x = <u>-5 +/- 1</u>
-4
x = <u>-5 + 1</u> or x = <u>-5 - 1</u>
-4 -4
x = <u>-4</u> x = <u>-6</u>
-4 -4
x = 1 x = 1.5
2y - 1 = x
2y - 1 = 1
<u> + 1 + 1</u>
<u>2y</u> = <u>2</u>
2 2
y = 1
(x, y) = (1, 1)
or
2y - 1 = x
2y - 1 = 1.5
<u> + 1 + 1 </u>
<u>2y</u> = <u>2.5</u>
2 2
y = 1.25
(x, y) = (1.5, 1.25)
The two solutions is equal to (1, 1) and (1.5, 1.25).
