$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad 
\begin{cases}
r=radius=\frac{diameter}{2}\\
h=height\\
----------\\
diameter=1.8\\
r=\frac{1.8}{2}=0.9\\
h=5
\end{cases}\implies V=\pi \cdot 0.9^2\cdot 5\\\\

Identify a possible first step using the elimination method to solve the system and then find the solution to the system. 2x – 3

omeli [17]

The answer is D

2x - 3y = 6 multiply this by -3
3x - y = 2 Multiply this by 2

-6x + 9y = -18
6x - 2y = 4 Add the 2 equations:-

7y = -14 so y = -2
Substitute y = -2 in second equation:-
3x - (-2) = 2
3x = 2-2 = 0
x = 0

solution is (0,-2)
