Suppose three spherical balls of wax with radius r are packed in
\n" ); document.write( " a cylinder also with radius r and the balls are melted down.
\n" ); document.write( " To what depth will the cylinder be filled.
\n" ); document.write( " The answer needs to be in terms of r.
\n" ); document.write( ":
\n" ); document.write( "Find the vol of the three balls in terms of r
\n" ); document.write( "V(r) = 3 * \"4%2F3\"*\"pi%2Ar%5E3\"
\n" ); document.write( "Cancel the 3
\n" ); document.write( "V(r) = \"4%2Api%2Ar%5E3\" cu/units is the volume of the wax
\n" ); document.write( ":
\n" ); document.write( "let d = the depth of the wax in the cylinder when melted
\n" ); document.write( "\"pi%2Ar%5E2%2Ad\" = \"4%2Api%2Ar%5E3\"
\n" ); document.write( "divide both sides by \"pi%2Ar%5E2\"
\n" ); document.write( "d = 4r units is the depth
\n" ); document.write( "
\n" ); document.write( "
\n" );
