You can put this solution on YOUR website!
Since the volume of a cylinder is pi*r2*h, we have:
\n" ); document.write( "V=pi(45)^2(12)
\n" ); document.write( "\"=pi(24300)
\n" ); document.write( "\"=76340.7 sq.ft.
\n" ); document.write( "You have to know how many gallons fit into a square foot of water to solve for gallons.
