The volume of a sphere with radius r can be found by the formula:
\n" ); document.write( "\"V=%284%2F3%29%2Api%2Ar%5E3\"
\n" ); document.write( "So the volume V of the tank is:
\n" ); document.write( "\"V=%284%2F3%29%2Api%2A0.25%5E3=0.0654m%5E3\"
\n" ); document.write( "The mass of the water can be found by multiplying V by p.\r
\n" ); document.write( "\n" ); document.write( "\"0.0654m%5E3%2A1000%28kg%2Fm%5E3%29=65.4kg\"\r
