The cylinder:
\n" ); document.write( "20 diameter
\n" ); document.write( "30 height
\n" ); document.write( "Volume:
\n" ); document.write( "[Pi(20/2)^2]*30 = 9424.78
\n" ); document.write( "Area, assuming the cylinder has a base (not an open hole):
\n" ); document.write( "Area base: Pi(20/2)^2 = 314.16
\n" ); document.write( "Area of the side:
\n" ); document.write( "(Pi*20)*30 = 1884.9
\n" ); document.write( "So, for the cylinder we have:
\n" ); document.write( "total volume = 9424.78
\n" ); document.write( "total area = 314.16+1884.9 = 2199.06
\n" ); document.write( "-----------------------------
\n" ); document.write( "The cone:
\n" ); document.write( "Height of 25 cm and a base diameter of 20cm
\n" ); document.write( "Volume:
\n" ); document.write( "[Pi(20/2)^2]*25/3 = 2617.99
\n" ); document.write( "Area, assuming the cone is connected to the cylinder so it has no base:
\n" ); document.write( "Pi(20/2)(20/2+sqrt(25^2+(20/10)^2 = 1102.07
\n" ); document.write( "Add the cone to the cylinder:
\n" ); document.write( "Volume cylinder 9424.78+2617.99 cone = 12,042.77
\n" ); document.write( "Area cylinder 2199.06+1102.07 cone = 3301.13
