the area of the base a right circular cone is 38.50 sq. cm.
\n" ); document.write( "find r, the radius
\n" ); document.write( "\"pi%2Ar%5E2+=+38.5\"
\n" ); document.write( "r = \"sqrt%2838.5%2Fpi%29\"
\n" ); document.write( "r = 3.5 cm
\n" ); document.write( " if its height is three times the radius of the base,
\n" ); document.write( "h = 3(3.5)
\n" ); document.write( "h = 10.5 cm is the height
\n" ); document.write( "find it's volume
\n" ); document.write( "V = \"1%2F3\"\"pi%2A3.5%5E2%2A10.5\"
\n" ); document.write( "V = 134.7 cu/cm is the volume
\n" ); document.write( ":
\n" ); document.write( "The area of a cone:
\n" ); document.write( "Find the slant height of the cone
\n" ); document.write( "s = \"sqrt%283.5%5E2%2B10.5%5E2%29\"
\n" ); document.write( "s = 11.07 cm is the slant height

\n" ); document.write( "A = \"pi%2A3.5%2A11.07\"
\n" ); document.write( "A = 121.7 sq/cm is the lateral surface area
\n" ); document.write( ":
