The radius of a cylindrical construction pipe is 1.5ft. If the pipe is 18ft long, what is its volume? Use the value 3.14 for π ,

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=1.5\\
h=18
\end{cases}\implies V=\pi \cdot 1.5^2\cdot 18$

Help me solve this problem please

y-12 $\geq$ -3y+3

add 12 to both sides

y $\geq$ -3y+15

add 3y to both sides

4y $\geq$ 15

divide both sides by 4

y $\geq$ 3.75 (or 3 and 3/4)

hope this helps!

F(x)=x3 −4x even odd or neither

Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

f(3) = 3³ - 4(3)
f(3) = 27 - 12
f(3) = 15 (odd)

Now, let's take an even number.

f(4) = 4³ - 4(4)
f(4) = 64 - 16
f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.
