The height of a cylinder is increased by a factor of 3. The radius is not changed. What is the effect of the increase on the vol
vagabundo [1.1K]
The answer should be A

original volume = Area x Height

If the the height was increased by a factor of 3,
Volume = Area x (Height x 3)

Which ultimately still means
Volume = (Area x Height) x 3

Which gives you the answer
Volume = (original volume) x 3

That's why the answer is A as the volume increased by a factor of 3

What is the area of the figure?
nirvana33 [79]

We can break it into two parts.

-> First, the rectangle on the bottom is made up of 2 feet x 16 feet. The formula for area of a rectangle is length times width, so in this case it is equal to 32 feet

-> Next, the triangle has sides of 10 feet, 10 feet, and 16 feet. We can calculate that the height is 6. The formula for area of a triangle is base times height divided by two, so, \frac{16*6}{2}= \frac{96}{2} = 48 feet

-> Last, we can add the two totals together. 32 feet + 48 feet = 80 feet giving us our final answer of 80 feet². As this answer is not pictured I am going to assume they are not including Heron's formula or other more complex formulas, leading us to the answer of "can't be determined"

Answer:

O can't be determined

Have a nice day! - <em>Note: It depends on the level of your math class for whether the answer "cannot be determined" is correct as it can be determined, just takes more effort than simple one - two-step formulas.</em>

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

If f(x)=25-2x, then f(5)=<br> Some please help
gizmo_the_mogwai [7]
F(x) = 25 - 2x

f(5) is pretty much the value of f(x) when x = 5

Plug x=5 into f(x)

f(5) = 25 - 2(5)
= 15

That's your answer.

Have an awesome day! :)
