Answer:
325pi m^3
Step-by-step explanation:
diameter of the base = 10 m
radius of the base = diameter/2 = 5 m
volume of cylinder = (pi)r^2h
Since the problem asks for the exact volume, we keep pi as pi, and we do not use an approximation of pi such as 3.14
r = 5 m
h = 13 m
volume = (pi)r^2h
volume = (pi)(5 m)^2(13 m)
volume = 25 * 13 * pi m^3
volume = 325pi m^3
Answer
248.3712
Step-by-step explanation:
2(H*W)+2(H*L)
2(5.78*6.72)+2(6.72*12.7)= 248.3712
The number of large boxes is 4 and the number of small boxes is 14.
<u><em>Explanation</em></u>
Suppose, the number of large boxes is
and the number of small boxes is 
As, the total number of boxes is 18, so the first equation is....

The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....

Now solving equation (1) for
itself , we will get....

We will plug this
into equation (2). So.....

Now plugging this
into the equation
.......

Thus, the number of large boxes is 4 and the number of small boxes is 14.
