Hey there Hailey!

So, to start this all of, what formula are we even going to use.

The formula that we will be using in this question would be . . .

\left[\begin{array}{ccc}\boxed{V= \pi r^2 \frac{h}{2}} \end{array}\right]

So, now that we know what formula that we will use, we will now plug in those number's into the formula.

Justification:

We do, 9 = (height)*3=(radius) \ but \ using \ the \ formula \ also.


\left[\begin{array}{ccc}27*3.14= \boxed{84.78} \\ Your \ correct \ answer \ would \ be \ \boxed{\boxed{27}}\end{array}\right]

Hope this helps you!

Please help on my hw, I'm not feeling good, and can't concentrate
sergiy2304 [10]

Answer:

Solution given:

f(x)=x²

g(x)=x+5

h(x)=4x-6

now

23:

(fog)(x)=f(g(x))=f(x+5)=(x+5)²=x²+10x+25

24:

(gof)(x)=g(f(x))=g(x²)=x²+5

25:

(foh)(x)=f(h(x))=f(4x-6)=(4x-6)²=16x²-48x+36

26:

(hof)(x)=h(f(x))=h(x²)=4x²-6

27;

(goh)(x)=g(h(x))=g(4x-6)=4x-6+5=4x-1

28:

(hog)(x)=h(g(x))=h(x+5)=4(x+5)-6=4x+20-6=4x-14
