If the height of a cylinder is tripled, but the area of the base stays the same, what happens to the volume?

The volume would double.

Here is an example:

The formula for the volume of a cylinder is:

V = (area of the base) x height

Now, let's plug in numbers to see what happens to the volume:

Let's say that cylinder 1 has a base area of 6 and a height of 10. Cylinder 2 would have a base area of 6 and a height of 20.

Let's plug in the values:

V1 = 6x10 = 60

V2 = 6x20 = 120

the volume doubles.

hope this helps :)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
