If a cone's radius and slant height are halved, then how will the new surface area compare to the old surface area?
\n" ); document.write( "Simplify your answer and write it as a proper fraction or as a whole or mixed number.
\n" ); document.write( "The new surface area will be _____ times the old surface area.
\n" ); document.write( ":
\n" ); document.write( "Total surface area formula
\n" ); document.write( "\"SA+=+%28pi%2Ar%2As%29+%2B+%28pi%2Ar%5E2%29\" where
\n" ); document.write( "r = the radius
\n" ); document.write( "s = the slant height
\n" ); document.write( "\"SA+=+pi%2Ar%28s+%2B+r%29\"
\n" ); document.write( ":
\n" ); document.write( "let the original cone be 2r and 2s, half would be just r and s
\n" ); document.write( "cancel pi*r, then cancel (s+r)
\n" ); document.write( "\"%28pi%2Ar%28s+%2B+r%29%29%2F%28pi%2A2r%282s%2B2r%29%29\" = \"%281%28s+%2B+r%29%29%2F%282%282s%2B2r%29%29\" = \"%281%28s+%2B+r%29%29%2F%284%28s%2Br%29%29\" = \"1%2F4\" of the old surface area
