Answer» The area formula is REALLY the formula for the CURVED surface (that is the 2πrh 2 π r h PORTION) added to the area of both ends (that is the 2πr2 2 π r 2 portion). If you see the PHRASE, "area of CYLINDER base," the writer is referring to the top and bottom ends, not the curved surface between them. |
