Answer:

$2.3\:\mathrm{in^3},\\1.3\:\mathrm{fl\:oz}$

Step-by-step explanation:

The volume of a cone with radius $r$ and height $h$ is equal to $V=\frac{1}{3}\cdot r^2\pi\cdot h$ .

What we're given:

Since radius is half the diameter, $r$ is $1.1$
Height of $1.8$

Substituting given values, we get:

$V=\frac{1}{3}\cdot 1.1^2\pi \cdot 1.8=0.726\pi\approx \boxed{2.3\:\mathrm{in^3}}$

Convert to fluid ounces using the conversion given in the question:

$0.726\pi}\cdot \frac{0.554}{1}\approx \boxed{{1.3\:\mathrm{fl\:oz.}}}$

The first three steps in determining the solution set of the system of equations, y = –x2 – 2x + 8 and y = 2x + 11, algebraicall

shutvik [7]

First step
Using substitution you can fill 2x + 11 in for the y part of the first equation
This will look like: 2x + 11 = -x^2 -2x + 8

Second step
Now we need to solve for the variable by combining like terms you can start by adding x^2 + 2x -8 to both sides
You get 0 = x^2 +4x +3

Third step
Factor
(X+3)(x+1)=0

If you need the y values you can fill in x= -3 to the second equation y= 2(-3) + 11 and y=5
First point is (-3,5)

The other point is found by filling x=-1 into the second equation: y= 2(-1) +11 and y = 9
Second point is (-1,9)
