4/3*pi*r^3 is the volume
\n" ); document.write( "The diameter is 3, so the radius is 3/2=1.5
\n" ); document.write( "Now find the volume which will equal the amount of water in the tank.
\n" ); document.write( "4/3*pi*1.5^3 Follow the order of operations:
\n" ); document.write( "4/3*pi*3.375
\n" ); document.write( "4/3*10.60
\n" ); document.write( "(4*10.60)/3 = 14.13 is the volume
\n" ); document.write( "I ran out of time. Divide 14.13 by 25/7 and you get your answer.
\n" ); document.write( "
