I just did this quiz (:
<span>The volume of the cylinder: V=r²π*H
V=7.5ft²
r=3ft
H=?
7.5=3²*π*H
7.5=28.274H⇒H=7.5/28.2740
H=0.265ft
</span><span>
The water level will be 0.265ft.</span>
Answer:
8.8 cm
Step-by-step explanation:
-We know that the top 20% of the books are oversized.
-We therefore find the z-value of the top 20%:

#We substitute the z value in formula to solve X.

Where
- X is the minimum thickness of the book.
-Given
, the minimum thickness,X can be calculated as follows:

Hence, the minimum thickness of the oversized books is 8.8 cm
Answer: 
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:

Where "r" is the radius and "h" is the height.
Make the conversion from inches to feet. Since
,you get:

So in this case you can identify that:

Then, substituting them into the formula and simplifying you get:

Therefore, the expression for the volume of L feet of drainage tubing, in cubic feet is:
