3x^2+23x-36

Step-by-step explanation:

The foil method is used when multiplying 2 binomials. One is (x+9) and another is (3x-4). The steps of FOIL are:

Multiply the first termsMultiply the outer termsMultiply the inner termsMultiply the last termsCombine like terms

Let's do the steps on our problem:

1. multiply x and 3x. So we have x * 3x = 3x^2

2. multiply x and -4. So we have x * -4 = -4x

3. Multiply 9 and 3x. So we have 27x

4. Multiply 9 and -4. So we have -36

Listing the terms, we have: 3x^2 -4x + 27x - 36

We combine like terms and have: 3x^2 + 23x - 36

That's our answer.

area = 40 $\pi$ $m^{2}$

vol = 32 $\pi$ $m^{3}$

Step-by-step explanation:

area :

cir = 2 $\pi$ i 2 = 4 $\pi$

area = $\pi$ 2^2 = 4 $\pi$

2(4 $\pi$ ) + 8(4 $\pi$ )

8 $\pi$ + 324 $\pi$ = 40 $\pi$

vol = 8 * 4 $\pi$ = 32 $\pi$
