Two designs for an oil storage tank are being considered: spherical and cylindrical.
\n" ); document.write( "The two tanks would have the same capacity and would each have an inside diameter of 30 feet. What would be the height of the cylindrical tank?
\n" ); document.write( ":
\n" ); document.write( "radius of both tanks = 15 ft
\n" ); document.write( ":
\n" ); document.write( "let h = the height of the cylinder
\n" ); document.write( ":
\n" ); document.write( "Cylinder vol = Sphere vol
\n" ); document.write( "\"pi%2Ar%5E2%2Ah+=+%284%2F3%29%2Api%2Ar%5E3\"
\n" ); document.write( "divide both sides by \"pi%2Ar%5E2\", resulting in a simple equation:
\n" ); document.write( "h = \"4%2F3\"r
\n" ); document.write( "h = \"4%2F3\"*15
\n" ); document.write( "h = 20 ft is the height
\n" ); document.write( "
\n" );
