Algebra.Com's Answer #104377 by mathgeek102(3)![]() ![]() ![]() You can put this solution on YOUR website! The formula for the surface area of a cone is:\r \n" ); document.write( "\n" ); document.write( "SA= pi r s + pi r squared\r \n" ); document.write( "\n" ); document.write( "r=radius\r \n" ); document.write( "\n" ); document.write( "s=slant height\r \n" ); document.write( "\n" ); document.write( "pi r s = area of the cone \n" ); document.write( "pi r squared = area of the base of the cone\r \n" ); document.write( "\n" ); document.write( "add them together to get the TOTAL area, or surface area around of the cone\r \n" ); document.write( "\n" ); document.write( "You do not need the height on the cone for surface area but for volume \n" ); document.write( "Therefore: \n" ); document.write( "SA= pi(7)(25) + pi(7)squared \n" ); document.write( "SA= 125 pi + 49 pi \n" ); document.write( "SA= 174 pi <- \"exact number\" using the symbol pi for an actual number \n" ); document.write( "use your calculator (pi button) or use the number 3.14159...\r \n" ); document.write( "\n" ); document.write( "Hope I helped! \n" ); document.write( " |
