Mathematics

In order to calculate the volume of a cylinder, we can use the following formula:

V=\pi r^2h

Where r is the base radius and h is the height.

If the circumference is 8, we have:

\begin{gathered} C=2\pi r \\ 8=2\pi r \\ r=\frac{4}{\pi} \end{gathered}

Now, calculating the volume, we have:

\begin{gathered} V=\pi(\frac{4}{\pi})^2\cdot10 \\ V=\frac{160}{\pi} \\ V=50.93 \end{gathered}

So the correct option is the second one.

A shelf can be packed from end to end with 30 large books or 45 small books.
DerKrebs [107]

Answer:

11

Step-by-step explanation:

since 30÷45 = 2/3 then

The space taken by a small book is equal to

the space taken by 2/3 a large book.

…………………………………………………

<u><em>Calculating the number of large book corresponding to 23 small books</em></u> :

= 23×(2÷3) + 3

= 18.333333333333 (large book)

Then ,Kevin can pack the shelf with (at most) : 30 - 19 = 11 more large books

Answer:

Step-by-step explanation:

hello

2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4  \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by  \ \ 2\\

so the solution is 2

5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4  \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by  \ \ 5

so the solution is 4/5

hope this helps
