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)
When making two logarithms one logarithm you keep the base (in this case that would be 2) and multiply the two numbers (in this case 7 times 6 = 42) so the answer is
