That other person, AS USUAL, is WRONG!! The total surface area is NOT .
\n" );
document.write( "Surface area of cone = Area of circular base + Lateral Surface Area, or , with r being radius, and l being slant height.
\n" );
document.write( "With r (radius) being 3 cm, if the height is 4 cm, then this represents a 3-4-5 right-triangle with a SLANT height (l) of 5 cm
\n" );
document.write( "We then have:  \n" );
