a SMALL JAR; cylindrical glass has radius 3 cm and height 7 cm,
\n" ); document.write( "the larger jar is similar to the shape
\n" ); document.write( "the glass is 216 times of the small jar.
\n" ); document.write( "Work out the radius and height of the jar
\n" ); document.write( ":
\n" ); document.write( "let r = the radius of the big jar
\n" ); document.write( "then
\n" ); document.write( "\"7%2F3\"r = the height of the big jar
\n" ); document.write( ":
\n" ); document.write( "The equation
\n" ); document.write( "\"pi%2A3%5E2%2A7%2A216\" = \"pi%2Ar%5E2%2A%287%2F3%29r\"
\n" ); document.write( "\":
\n" ); document.write( "\"pi%2A13608\" = \"pi%2A%287%2F3%29r%5E3\"
\n" ); document.write( "divide both sides by pi
\n" ); document.write( "13608 = \"7%2F3\"r^3
\n" ); document.write( ":
\n" ); document.write( "\"r%5E3\" = \"3%2F7\"*13608
\n" ); document.write( ":
\n" ); document.write( "\"r%5E3\" = 5832
\n" ); document.write( "find the cube root of both sides
\n" ); document.write( "r = \"5832%5E%281%2F3%29\"
\n" ); document.write( "r = 18 cm is the radius of the big jar
\n" ); document.write( "and
\n" ); document.write( "\"7%2F3\"*18 = 42 cm is the height
\n" ); document.write( "
\n" );
