a) 15 foot diameter means we have a 7.5 foot or 90 inch radius, then
\n" ); document.write( "Volume(V) = pi * 90 * (1/8) = 35.342917358 cubic inches
\n" ); document.write( "there are 1.8 cubic inches in a liquid ounce, therefore
\n" ); document.write( "you need 35.342917358 / 1.8 = 19.6 liquid ounces or 2.5 liquid cups
\n" ); document.write( "b) 18 foot diameter means we have a 9 foot or 108 inch radius, then
\n" ); document.write( "Volume(V) = pi * 108 * (1/8) = 42.411500829 cubic inches
\n" ); document.write( "there are 1.8 cubic inches in a liquid ounce, therefore
\n" ); document.write( "you need 42.411500829 / 1.8 = 23.6 liquid ounces or 3 liquid cups
\n" ); document.write( "
\n" );
