<span>Step 1: find the radius
The radius is half of the diameter. So the radius is 8 because the diameter is 16.
Step 2: square the radius.
8^2 = 64
Step 3: plug into formula
pi * radius squared * height
3.14 * (64) * (1.8) = 361.728 m^3
The volume of the pool is 361. 728 meters cubed.
Step 4: Divide volume by the amount pumped out per hour
volume / amount pumped out = amount of hours
361.728/16 = 22.608 hours.
So your answer is approximately 23 hours.</span><span>

Answer:
Hi there!
The answer to this question is: 7
Step-by-step explanation:
You simply plug in the values given and solve
8(1/2) + 3(7) -18
4+21-18=7
Answer:
apparently just label each part ( a, b, c, d, so on) and tell the order/ switch em around
Step-by-step explanation:
Answer: x=-7/2 y=29/2
Steps:
Use the elimination method
Multiply -3x+y=4 by 5 to make the coefficient next to the y in both equations the same
5(-3x+y=4)
-15x+5y=20
Then, subtract to eliminate the y
-15x+5y=20
- -9x+5y=-1
= -6x=21
Divide both sides by -6 to isolate x
= x= -7/2
Next substitute -7/2 into x in one of the equations
-3(-7/2)+y=4
-21/2+y=4
Add 21/2 from both sides to isolate y
y=29/2
