Find the surface area of a right circulr cone:
\n" ); document.write( "Note:
\n" ); document.write( "The \"lateral surface\" area (S) of a cone does not include the area of the base.
\n" ); document.write( "The \"total surface\" (T) area of a cone included the area of the base.
\n" ); document.write( "Let's do both and you can choose which anwer is appropriate.
\n" ); document.write( "1) Lateral surface area (area of base not included) is:
\n" ); document.write( "\"S+=+pi%2Ar%2As\" where: r is the radius of the base and s is the slant height.
\n" ); document.write( "\"S+=+pi%2A5%2A12\"
\n" ); document.write( "\"S+=+60%2Api\" sq.in. This is the exact answer.
\n" ); document.write( "\"S+=+188.4\" sq.in. This an approximate answer. (I just multiplied by 3.14 for \"pi\".
\n" ); document.write( "2) Total surface area (area of base is included) is:
\n" ); document.write( "\"T+=+pi%2Ar%28r%2Bs%29\" where: r is the radius of the base and s is the slant height.
\n" ); document.write( "\"T+=+pi%2A5%285%2B12%29\"
\n" ); document.write( "\"T+=+pi%2A5%2817%29\"
\n" ); document.write( "\"T+=+85%2Api\" sq.in. This is the exact answer.
\n" ); document.write( "\"T+=+266.9\" sq.in. This an approximate answer. (I just multiplied by 3.14).
\n" ); document.write( "
\n" ); document.write( "
\n" );
