What is the total surface area of a cylinder? Write your answer as a polynomial in standard form.

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)
