1. LATERAL AREA of a CYLINDER GEO182 A cylinder has 3 main pieces: the bases (circles) and the lateral surface (rectangle). TopBottom LS r

2. LATERAL AREA of a CYLINDER GEO182 NOTE: the length of the wall is the circumference of the circle! The lateral surface area (LSA) is the area of the sides which is the distance around the circle (base) times the height. C =  d Height A = bh Flatten out the circular wall into a rectangle. LSA Formula = (circumference of base)(height) h
