volume of cylinder $\"v+=pi%2Ar%5E2%2Ah\"$
\n" ); document.write( " curved surface area $\"+a=+2%2Api%2Ar%2Ah\"$
\n" ); document.write( "where r = radius
\n" ); document.write( " h=height
\n" ); document.write( " but v=1650 cubic cm
\n" ); document.write( " a = 660 sq cm
\n" ); document.write( " $\"+v%2Fa++=%28pi%2Ar%5E2%2Ah%29%2F%282%2Api%2Ar%2Ah%29\"$
\n" ); document.write( " $\"v%2Fa++=r%2F2\"$
\n" ); document.write( " $\"1650%2F660+=r%2F2\"$
\n" ); document.write( " $\"5%2F2=r%2F2\"$
\n" ); document.write( " $\"%285%2F2%29%2A2+=+r\"$
\n" ); document.write( " $\"5=r\"$
\n" ); document.write( " hence radius (r)= 5 cm
\n" ); document.write( " $\"+a=+2%2Api%2Ar%2Ah\"$
\n" ); document.write( " $\"+660+=2%2A3.14%2A5%2Ah\"$
\n" ); document.write( " $\"+660+=31.4+%2Ah\"$
\n" ); document.write( " $\"660%2F31.4+=h\"$
\n" ); document.write( " $\"21.09=h\"$
\n" ); document.write( " hence height = 21 cm ( approximately) \n" ); document.write( "

\n" );
