if the total surface area of a solid hemisphere is 460 cm square.find its volume
\n" ); document.write( "------------
\n" ); document.write( "SA for a sphere is 4pi*r^2
\n" ); document.write( "The SA for the round part of a hemisphere = 2pi*r^2
\n" ); document.write( "The flat part is pi*r^2
\n" ); document.write( "--> 3pi*r^2 = 460
\n" ); document.write( "\"r+=+sqrt%28460%2F3pi%29\"
\n" ); document.write( "r =~ 6.98624 cm
\n" ); document.write( "-----------
\n" ); document.write( "\"Vol+=+2pi%2Ar%5E3%2F3\"
\n" ); document.write( "= 714.1487 cc
\n" ); document.write( "
\n" );
