\n" ); document.write( "The formula for the volume of a right cone with radius r and height h:

\n" ); document.write( " $\"V=%281%2F3%29%28pi%29%28r%5E2%29%28h%29\"$

\n" ); document.write( "The given volume is 4125pi units; the diameter is 30 units, so the radius is 15 units.

\n" ); document.write( " $\"4125%28pi%29=%281%2F3%29%28pi%29%2815%5E2%29%28h%29\"$
\n" ); document.write( " $\"12375=225h\"$

\n" ); document.write( " $\"h=12375%2F225=55\"$

\n" ); document.write( "ANSWER: The height is 55 units

\n" ); document.write( " \n" ); document.write( "
