You can put this solution on YOUR website!
If J = the amount of juice in fluid ounces and D = its diameter, then:
\n" ); document.write( "\"J+=+kD%5E3\" where k = the constant of proportionality.
\n" ); document.write( "To find the value of k, substitute D = 3 and J = 3.
\n" ); document.write( "\"3+=+k%283%5E3%29\" Evaluate.
\n" ); document.write( "\"k+=+3%2F27\"
\n" ); document.write( "\"k+=+1%2F9\"
\n" ); document.write( "To find the amount of juice when D = 6...
\n" ); document.write( "\"J+=+D%5E3%2F9\" Substitute D = 6.
\n" ); document.write( "\"J+=+6%5E3%2F9\"
\n" ); document.write( "\"J+=+216%2F9\"
\n" ); document.write( "\"highlight%28J+=+24%29\" fl.oz. You got it!\r
