 Lateral Surface Area : S = ½ P l  P represents the perimeter of the base and l represents the slant height  Total Surface Area : S = ½ P l + B  B represents the area of the base

 Lateral Surface Area : S = πr l  l represents the slant height  Total Surface Area : S = πr l + πr 2 Slant height Height Radius
