Answer: The answer is B. Because 3 multiplied by x and add it by 3 equates to y. example: (x=2) 3x2+3= y. y=9 .
<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>
