\bf \stackrel{\textit{volume of a cylinder}}{V=\pi r^2 h}\qquad \qquad \stackrel{\textit{volume of a cone}}{V=\cfrac{\pi r^2 h}{3}}\\\\
-------------------------------\\\\
\stackrel{\textit{volume of this cylinder}}{\pi (4)^2(12)}~~+~~\stackrel{\textit{volume of this cone}}{\cfrac{\pi (4)^2(6)}{3}}

192\pi ~+~32\pi \implies 224\pi

V of a cylinder = pi x r^2 h

V of a cone = 1/3 x pi x r^2 h

Can someone please help ? :(

Answer:

I'll list the answers as coordinates (just input the second number in each coordinate)

(-2, 11)

(0, 1)

(2, -9)

(4, -19)

Step-by-step explanation:

So you see how the x column is filled out? You plug in the numbers in each area and solve for y.

So we start off with -2. You take the x out and place -2 instead. Your equation should look like this:

y = -5 (-2) + 1

Next you multiply -5 and -2, giving you 10. Your equation would look like this now:

y = 10 + 1

Next you add 10 and 1 together, and you have your answer. Keep doing the same thing, but instead of -2 for x, use 0, 2, and 4.

Hope I helped! Have a nice day or night! ^-^
