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)
0.25e − 14 = 26 Then you add 14 from both sides
0.25e=40 Then you divide both sides by 0.25
e=160
Then to check you work you do this:
0.25(160)-14=26
40-14=26
26=26 Correct!!!!

1. x = 15120/12 = 1260 (monthly salary)
2. 1200 x 0.05 = 60 (raise)
Check: 1200+60=1260
Its d if you need an explanation I can tell you
