Step-by-step explanation:
diameter = 4cm
radius = 4/2 = 2cm
height = 3cm
volume of cylinder = πr²h
= 22/7 × 2 × 2 × 3
= 264/7cm³
= 37.714cm³
Haha wring subject but convergent

Step-by-step explanation:
(8x - 7)(
The x^2 term has to come out to 8x^2.
The 8 is already there.
So your first term in the second factor is x.
(8x - 7) ( x
Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.
Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.
(8x - 7)(x -
Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.
That should be a one.
(8x - 7)(x - 1)
x - 1 is you answer. I leave you to check the middle term. It is - 15
X^3 +x^2 +x +1 = x^2(x +1) + x +1 = (x^2 +1)(x +1)
hope helped
