Okay! A cylinders area is found by the following equation.

A = πr²h

We need to find the radius, which is half of the diameter. So the radius is 5.5 in.

A = π(5.5)²h

There is no provided height in the question you asked, but I will simplify as much as possible so if you have the height, you can simply plug it in!

A = 30.25πh in³

Remember π is the symbol for the irrational number 3.1415... Regardless, plug that into a calculator with the provided height and you’ll have your answer.

HERE ARE TWO NUMBER MACHINES A AND B

nika2105 [10]

Answer:

$x=-7$

Step-by-step explanation:

We can write them both like functions like this

$A=5x-4$

$B=3x+8$

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

$A=3B$

we replace with the functions

$5x-4=3(3x+8)$

we solve for x

$5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7$

The output that makes the out put of A 3 times teh output of B is $-7$

Find the surface area of a cylinder that has a raius of 13.5 cm., and a height of 90 cm. Show all work without using a calculato

professor190 [17]

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=13.5\\ h=90 \end{cases}\implies SA=2\pi (13.5)(90+13.5) \\\\\\ SA=27\pi (103.5)\implies SA=2794.5\pi \implies SA\approx 8779.18$

well, the last part will be with a calculator, but you can simply use the area in π terms.
