Answer:
If we take the adjacent side AD and DC and work out their slopes we get
AD = (6-4)/(2-0) = 1 and DC has slope (6-4)/(2-4) = -1 . This shows that the angle between the 2 lines is 90 degrees so it looks like this is a square. If you include the slopes of each adjacent line they are at right angles too. Now to prove its a square each line must be of equal length and you'll find this is the case too
Height of cylinder = ft
Diameter of cylinder = times its height = ft
Now Radius = half of diameter = ft
Now we have to find the Volume of cylinder
formula for Volume of cylinder is
Volume of cylinder =
let's plug the values
Volume of cylinder =
Plug the values in calculator
= 11852.9657 cubic feet
Round off the answer to two decimal places(i.e. hundredth)
= 11852.97 cubic feet

X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
