You can put this solution on YOUR website!
Let C = capacity of spherical gas tank.\r
\n" ); document.write( "\n" ); document.write( "You are given a 45 foot diameter. We need to find r, which is the radius.\r
\n" ); document.write( "\n" ); document.write( "The radius is 1/2 the diameter.\r
\n" ); document.write( "\n" ); document.write( "So, radius is 45/2 = 22.5\r
\n" ); document.write( "\n" ); document.write( "C = (4/3)(3.14)(22.5)^3\r
\n" ); document.write( "\n" ); document.write( "Before finding C (your answer), we must raise 22.5 to the third power.\r
\n" ); document.write( "\n" ); document.write( "22.5 x 22.5 x 22.5 = 11390.625\r
\n" ); document.write( "\n" ); document.write( "Now, C = (4/3)(3.14)(11390.625)\r
\n" ); document.write( "\n" ); document.write( "Of course, we can also write 3/4 as 0.75 giving us the equation\r
\n" ); document.write( "\n" ); document.write( "C = (0.75)(3.14)(11390.625)\r
\n" ); document.write( "\n" ); document.write( "Can you finish now?\r
\n" ); document.write( "\n" ); document.write( "Just multiply using your calculator to find C.\r
\n" ); document.write( "
