Answer:
Ok to find the surface area of this cylinder first we need the circumference to find this we do C=πd
C=3.14*18
C=56.52
now we have to multiple this by the height of two
113.04
now we have to find the area of the bottom to do this we do A=πR^2
A=3.14*81
A=254.34
multiple this by two for the two sides we get
508.68
now we add this to 113.04 we get
621.72
since I used 3.14 instead of more digits of pie we can round this up so the answer is C.
Your Welcome
BIFFY OUT!!!
H=v/(2pir)
You just have to isolate h. To do that you are going to divide both sides by 2pir.
Answer:
<h2>A = 2.25π</h2>
Step-by-step explanation:
The formula of an area of a circle:

r - radius
The formula of a circumference of a circle:

We have:

Substitute:
<em>divide both sides by 2π</em>

Substitute:

Answer:
A property of a function is that it gives one output for an input
if a function gives one output for an input, it is a function and otherwise it is not a function otherwise
here, we can see that we have 2 outputs for the input '6'. therefore, it is NOT a function
