Answer:
The first one is ur answer
Step-by-step explanation:
The volume of a cylinder is pi*r^2*h
The radius is half the diameter, so 40/2=20, and the radius is 20 ft.
Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597
So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32
Hope this helped!
For the very last part, a is 29 and b is 45.
<span>Part 1:

option b.
Part 2:

option d
Part 3:

Multiply through by the LCM of 2 and 3 (i.e. 6)

option b
Part 4
x^2-3x-8=x+4

option d
Part 5
Joseph is solving the equation x^2+8x-4=0 using the technique completing the square.
x^2+8x-4=0
x^2+8x+?=4+?
In completeing the square method, you divide the coeficient of x by 2, square the result and add to both sides of the equation.
Therefore, he should add 16 to both sides because (8/2)^2=16.
option d.
