Surface area of a cylinder=area of 2 bases+area of around cylinder
area of bases=area of circle os 2 times pi times r^2
area of around=circunferenc of circle times height of cylnder=2 timespi timer r times height so 2pirh
so add
area of bases+area around=2pir^2+2pirh
not sure what standard form is
so he answer is
2pi(r^2)+2pi(r)(h)

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

$y = \frac{x^2 -1}{2x + 1}$

therefore $\\\frac{dy}{dx}\\$ is

$\frac{d\frac{x^2 -1}{2x + 1}}{dx}$

$\frac{\frac{x^2 -1}{2x + 1}}{x}$

$\frac{x^2 -1}{(2x+1) x}$

Now

$\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx$

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....
