Answer: Volume=502.7 oz
Explanation: We need to find the volume of this cylinder to answer the question.
The general formula for the volume of a cylinder is V=πr^2h
Substituting gives us V=π*8*20, then V=160π and finally V=502.6548246 oz cubed
Let
x-------> the number of fiction books
y-------> the number of nonfiction books.
we know that
-----> equation 
-----> equation 
Add equation
and equation 
<u>find the value of y</u>



therefore
<u>the answer is</u>
Part a) the number of fiction books is
