Algebra.Com's Answer #73220 by doukungfoo(195)![]() ![]() You can put this solution on YOUR website! The volume of a cone is equal to area of the base times the height times 1/3 \n" ); document.write( "The base of a cone is a circle. \n" ); document.write( "Area of circle equals \n" ); document.write( "To use this formula we need the radius but all that is given is the diameter \n" ); document.write( "so to find radius just divide diameter by 2 \n" ); document.write( "6/2=3 \n" ); document.write( "The radius is 3 feet. \n" ); document.write( "Now we can find the area of the base. Use 3.14 for \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Now we can use the volume formula to find the height of the cone. \n" ); document.write( "volume=(area of base)(height)(1/3) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So a good estimate for the height of the cone shaped water tank is \n" ); document.write( "10.6 feet\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
