Find the total surface area of a closed cylinder having a diameter of 1.000 m and 15.000 mm and a length of 12.000 m and 55.000 mm.
(Round the answer to 3 decimal places)
1 m = 1000 mm
Total surface area= pi*D*h+2*(0.7854*D^2)

Do you have one or two cylinders?
total area of a cylinder of radius r and height h is
= the two circles + "sleeve"
= 2πr^2 + 2πrh
sub in the values once you have decided who goes where.
