Answer:1 and 2

Step-by-step explanation:

Given

Volume needed $V=220\ in.^3$

For first cylinder

$r=3\ in.$

$h=4\ in.$

$V=\pi r^2h$

$V_1=\pi (3)^2(4)$

$V_1=113.11\ in^3$

For second cylinder

$r=4\ in.$

$h=4\ in.$

$V=\pi r^2h$

$V_2=\pi (4)^2(4)$

$V_2=201.08\ in^3$

For Third cylinder

$r=9\ in.$

$h=9\ in.$

$V=\pi r^2h$

$V_3=\pi (9)^2(9)$

$V_3=2290.51\ in^3$

For fourth cylinder

$r=4\ in.$

$h=9\ in.$

$V=\pi r^2h$

$V_4=\pi (4)^2(9)$

$V_4=452.448\ in^3$

So, cylinder $1$ and $2$ are appropriate as it is under $220\ in.^3$

What numbers add up to -5 and multiply to get -90

Molodets [167]

Let
x-------> the first number
y-------> the second number

we know that

$x+y=-5 \\ x=-5-y$ equation 1

$x*y=-90$ equation 2

substitute the equation 1 in equation 2

$[-5-y]*y=-90 \\ -5y- y^{2} =-90 \\ y^{2} +5y-90=0$

using a graphical tool to resolve the second order equation
see the attached figure
the numbers are
-12.311
7.311

We know the length and width. We're just trying to find all of the area in between. To find area, we do length*width. Length is 11.5 and the width is 10.75. 11.5*10.75=123.625 ft^2
